Product: RealPlayer 4.0, RealPlayer Plus 4.0

Problem: Can I use RealPlayer 4.0 with the AOL 3.0 Web browser on Windows 95/NT?

Recommended Solution: The RealPlayer 4.0 and RealPlayer Plus 4.0 are compatible with the AOL 3.0 browser for Windows 95/NT. Here are 4 steps to verify you have compatible versions of the AOL browser and Player software configured correctly.

1. Verify your computer has the correct version of the AOL browser, 3.0 2. Download and install the RealPlayer 4.0, or RealPlayer Plus 4.0 version. 3. Manually configure AOLs browser to recognize the RealPlayer 4.0 4. Test the Player; try it out on some cool files!

1. Verify upgrade to AOL 3.0 browser for Windows 95

America Online's current browser is 3.0. There are two versions of this browser, one for Windows 3.1.x, and one for Windows 95/NT. You need the Windows 95/NT version to be compatible with the 4.0 RealPlayer or Plus version.

The RealPlayer and RealPlayer Plus 4.0 are currently available for Windows 95/NT (not available yet for Windows 3.1.x).

Using the Windows 95 or Windows NT computer system, please download and install the 32-bit AOL 3.0 browser for Windows 95/NT for compatibility with the RealPlayer 4.0 or RealPlayer Plus.

AOL members can download the Windows 95 version of the AOL 3.0 browser for free. Sign on to AOL, select the "Keyword" icon, and when the dialog box appears type the word "upgrade". The screen for the AOL 3.0 browser will come up and walk you through the upgrade steps.

2. Download and Install RealPlayer 4.0

Once you have installed AOL's browser, you will need to install the RealPlayer 4.0. To get the latest version of RealPlayer, go to the following Web site:

http://www.real.com/products/Player/Playerdl.html

If you are using Player Plus, you can download the latest upgrade for RealPlayer Plus from your Personal Timecast Page or from the following web site:

http://www.real.com/products/Playerplus/4.0Download.html

Once the file is downloaded to your hard drive, double-click on the file to start the installer. During installation of the Player, when you are asked to select a browser, choose Microsoft Internet Explorer.

3. Manually Configure the 3.0 AOL Browser

Once you have installed the AOL browser and RealPlayer, manually configure the browser to automatically launch the RealPlayer whenever you click on a RealAudio or RealVideo link. Follow the steps below:

A. Launch AOL 3.0 after installing the RealPlayer
B. From the menu bar, click on the "Globe" (internet) Icon.
C. Select the "Prefs" button in the menu at the top
D. Click on the "Programs" tab
E. In the Viewers section, click on the "File Types..." button
F. Select "RealAudio File" in the "Registered file types" list
G. Click the "Edit..." button
H. Verify that "open" is listed in the window under Actions
I. Click on the "Edit..." button
J. Verify that the path name in the "application used to perform action:" field is correct, ie references the rvPlayer.exe. If it is not, browse to where rvPlayer.exe is located on your computer (default is in c:\real\Player\rvPlayer.exe) and click OK.

If a RealAudio entry does not exist in the "File Types", follow these steps:

A. Click "New Type"
B. In the "Description of type" field, enter "RealAudio File"
C. In the "Associated extension" field, enter ".ram"
D. In the "Content Type (MIME)", enter "audio/x-pn-RealAudio"
E. Click on the "New..." button
F. Type "open" in the "Action:" field
G. Type "C:\real\Player\rvPlayer.exe" ("path name") in the "Application used to perform action:" field

If you have installed the RealPlayer into a different directory put your path name in the "Application used to perform action:" field or select browse, then select the path to the rvPlayer.exe application.

4. Test the Player

Test your installation by pointing the AOL browser to
http://www.timecast.com
and select RealAudio links from the Audio Guide and RealVideo links from the Video Guide.

Player Plus users may wish to try out the Plus Zone, by choosing the Sites menu item within the Player Plus, and selecting PlusZone.

Note for Windows 3.1.x users:
If your system is running Windows 3.1.x, use the RealAudio 3.0 Player. RealNetworks will release a 16-bit version of RealPlayer 4.0 for Windows 3.1.x sometime in the near future.

Question: I have a comment or question for NPR.

Solution:
If you have comments you would like to send to NPR directly, please see the following web site for the appropriate email address:

http://www.npr.org/inside/contactnpr/

Here are the answers to several common questions about NPR:
Q. Why are all programs not available?
A. Progressive Networks relies on NPR to provide the RA files. However, NPR frequently edits out some stories on its programs, making them unavailable to us and to our users. If you are interested in obtaining unavailable content, NPR provides tapes of its broadcasts.

Q. Why is there a delay of a few days in shows appearing on the Web site?
A. The editing process takes time, which is the reason for delays in providing NPR content on our site.

Q. Can I do a search of the NPR archive?
A. We are unable to provide a search engine for the NPR content due to copyright laws.

Product: RealAudio Player 2.0

Question: When trying to listen to the 'play here', the Macintosh version of the RealAudio Player 2.0 tries to download a .ram file.

Solution:
When the RealAudio Player 2.0 for Macintosh tries to download a .RAM file instead of playing the audio file, the helpers for the browser need to be reconfigured.

There are two ways to reconfigure the browser. One is to reinstall the RealAudio Player; the installation process will automatically configure the browser for you. The second is to manually configure the browser.

To manually configure the web browser, follow these steps:

1) Start Netscape Navigator and select the General Preferences menu items from the Options menu.

2) Select the tab "Helpers"

3) When the Helper Application window opens, select the New button and enter the following information in the appropriate box:

Description: RealAudio
MIME Type: audio/x-pn-realaudio
Suffixes: ra,ram

4) Press the "Application" radio button and find the directory that the RealAudio Player was installed (the default is the RealAudio folder on your startup volume) then select the RealAudio Player as the application to launch.

5) Select "PNRM" in the "File type" pull-down menu.

6) Select OK.

You may also have to manually configure the Plugin for the RealAudio Player:

1) Start Netscape Navigator and select the General Preferences menu items from the Options menu.

2) Select the tab "Helpers".

3) When the Helper Application window opens, select the New button and enter the following information in the appropriate box:

Description: audio/x-pn-realaudio
MIME Type: audio/x-pn-realaudio
Suffixes: rpm

4) Press the "Plug-in" radio button and select the RealAudio Plugin in the pull-down menu.

5) Select OK.

If, after having reinstalled the RealAudio Player or reconfiguring the browser for the RealAudio Player, the browser continues to have problems launching RealAudio, you should rebuild the desktop file. To rebuild the desktop file on a Macintosh, shut the system off, then start it up, holding down the Option and Command keys.

Product: RealPlayer 4.0, RealPlayer Plus 4.0

Question: I installed RealPlayer 4.0 but when using RealPlayer with Microsoft Internet Explorer 3.0, it causes various error messages or launches version 2.1 of RealAudio.

Solution:
Microsoft Internet Explorer 3.0 installs a version of RealAudio 2.1 during its installation process. Various errors and behaviors may indicate that this older version, the RealAudio Player 2.1 is still present on your system. The older version may also launch instead of RealPlayer or RealPlayer Plus 4.0. To correct this, make a clean installation of just the RealPlayer 4.0 components by eliminating all prior versions of the Player, and then reinstalling RealPlayer 4.0.

If you are using Player Plus, be sure to locate your serial number before starting this process. You will need it to reinstall. This number can be found on the back of the CD case, if you purchased the boxed product, in the About dialog box, found off of the Help menu, of later versions of Player Plus, or in the confirmation e-mail Progressive Networks sent after you purchased the product on-line.

Start the elimination process by removing all RealAudio software from the system by deleting the "raPlayer" and "real" directories, and any other files related to these applications. These are detailed as follows:

Question: How do I configure the Macintosh RealAudio Player to play rather than download a .ram file.

Solution:
When the RealAudio Player 3.0 for Macintosh tries to download a .RAM file instead of playing the audio file, the helpers for the browser need to be reconfigured.

There are two ways to reconfigure the browser. One is to reinstall the RealAudio Player; the installation process will automatically configure the browser for you. The second is to manually configure the browser.

To manually configure the web browser, follow these steps:

1. Start Netscape Navigator from the Options menu select the General Preferences option.

5. Select "PNRM" in the "File type" pull-down menu.
6. Select OK.

You may also have to manually configure the Plugin for the RealAudio Player:

Product: RealAudio Player 2.0

Question: When I try to install the RealAudio Player 2.0 it says "Can't find airmos.exe"

Solution:
When the RealAudio Player 2.0 is installed, it looks for the browser in the Path (Windows 3.1x) or in the Registry (Windows 95) during the configuration process. If AirMosaic has been deleted, and this was the default browser, the error "Can't Find AirMOS.EXE" will occur.

There are two possible solutions to this. One is to reinstall the browser and then reinstall the RealAudio Player. The second is to click the Cancel button during the RealAudio installation, launch your system's current browser, and reinstall the RealAudio Player. Either of these options will allow the RealAudio Player to run through the code that configures the browser helper.

It is possible that you will need to manually configure the browser helpers for the RealAudio Player after installation if the default browser is not found during this process.

Manual configuration procedure for Netscape Navigator:
1. Start Netscape Navigator and select the General Preferences menu items from the Options menu.
2. Select the tab "Helpers"
3. When the Helper Application window opens, select the New button and enter "audio" in the Mime type field and "x-pn-realaudio" in the Mime subtype field select "OK"
4. Enter "ra,ram" in the Extensions field.
5. Press the "Launch Application" radio button and find the directory that the RealAudio Player was installed (the default is the RealAudio folder on your startup volume) then select the RealAudio Player as the application to launch.
6. Select "PNRM" in the "File type" pull-down menu and select OK.

Note that most browsers have helper preferences that the user can manually configure.

Question: I have installed RealAudio Player 3.0 or RealAudio Player Plus 3.0 on a system with Microsoft's Internet Explorer 3.0x and I'm getting various error messages from my Player.

Solution:
Microsoft Internet Explorer 3.0 installs a version of RealAudio 2.1 during its installation process. Various errors and behaviors may indicate that this older version, the RealAudio Player 2.1, is still present on your system. The older version of the Player may also launch instead of RealAudio Player 3.0 or RealAudio Player Plus 3.0.

Product: RA Encoder 3.0

Question: My ISP uses a RealAudio 1.0 or 2.0 Server. Where can I get a RealAudio 1.0 or 2.0 Encoder, my ISP only provides a 1.0 or 2.0 Server.

Solution:
If your ISP provides only a RealAudio 1.0 or 2.0 server and you need to encode files to play on these older servers, use the RealAudio 3.0 version of the Encoder.

The RealAudio 3.0 Encoder has ten encoding algorithms, including the original RA 1.0 algorithm, 14.4, and the RA 2.0 algorithm, 28.8. Thus, the 3.0 Encoder can be used to create 14.4 RA or 28.8 RA files.

The RealAudio 1.0 Server can serve 14.4 RA files. The 2.0 version of the Server can serve both 14.4 RA and 28.8 RA files.

If you are renting RealAudio streams from an ISP, and need to use the live Encoder, contact your ISP to use theirs. The 3.0 Encoder cannot be used in conjunction with the RealAudio 2.0 Server to serve live streams. Note that the 1.0 Encoder cannot do Live Streams.

Product: RealPlayer 4.0, RealPlayer Plus 4.0

Question: I receive an "Expired" error message on RealPlayer 4.0 or RealPlayer Plus 4.0, even after reinstalling the 4.0 version.

Solution:
If RealPlayer 4.0 or RealPlayer Plus 4.0 continues to give you a message that the version has expired, even though you have just reinstalled the 4.0 version, this may be due to a variety of causes. To remedy this error, do a clean installation with the most current version of the RealPlayer 4.01 or RealPlayer Plus 4.01.

Performing a clean install removes any old RealPlayer components from your system, including the Player's preferences file. This will help verify that your Player is correctly installed and eliminates possible errors due to older libraries, and other components in use.

To delete all Player components from your Macintosh, perform the following steps:
1. From the desktop Finder menu, select File, then select Find File
2. Within the Find File dialog box, under 'Find files on local disks whose names contain __" type the word "real"', click Find.
3. Select all the files that appear by pressing the "command (Apple)" and "a" keys.
4. Verify that no files selected are personal files with the word "real" in them. To deselect those you wish to keep, hold down the shift key as you select them.
5. If you wish to keep the Player Installer you already downloaded, hold down the shift key and deselect the Player Installer by clicking on it from the list of files.
6. Drag all of the files to the trash.
7. You can empty the trash at this point if you like.

To reinstall the Player, restart your computer with only the System 7.x Extensions. To verify you are using these system extensions:
1. From the Apple Menu, select the Control Panel.
2. Select the Extension Manager.
2. If you are using a custom extension set, name the current set of extensions you are using. To do this, select "Save Set" from the drop down "Set" menu and assign them a name.
3. Select "System 7.x" from the "Sets" drop down menu.
4. Restart your Macintosh.

This will temporarily disable non-essential extensions which may conflict with software installation. The system will now have only the standard set of Apple's features and extensions turned on, including Internet connectivity. This enables the Player installer to complete the part of the installation procedure which takes you to content on the Internet.

Once you have restarted with System 7.x Extensions only, run the Player installer. After you have finished successfully you may wish to rebuild your desktop file.

Apple recommends that you rebuild the desktop file after you install new software. To rebuild the desktop file, hold down the "Command" and "Option" keys while you restart the computer. Keep the keys held down until you see an alert reading "Are you sure you want to rebuild the desktop file on the disk "nameofhardrive"?" Release the keys and click "OK". This process may take several minutes.

If you wish to return to the custom set of extensions you were using before you installed the Player, select your saved custom Extension Set in the Extension Manager.

Finally, reinstall the RealPlayer or RealPlayer Plus 4.01. The RealPlayer can be downloaded for free from:

http://www.real.com/products/Player/Playerdl.html

To redownload the RealPlayer Plus, within the RealPlayer Plus Sites menu item choose PlusZone. From the PlusZone page, click on Upgrade Subscription, and click on Upgrade Now. You can also download RealPlayer Plus from the following Web site:

http://www.real.com/products/Playerplus/4.0Download.html

We regret any frustration this may have caused you.

Should installing the Player present further difficulties, please provide more detailed information to Progressive Networks Technical Support Engineers at:

Question: Where do I find the cevents compiler in RealVideo Encoder 4.0 beta?

Solution:
There is a new tool to compile synchronized multimedia files in the RealVideo Encoder 4.0 beta. It is called RMMerge, and replaces the cevent compiler that used to be in the RealAudio Encoders 2.0 and 3.0.

In order to compile synchronized multimedia files, you will need the cevent32.dll (or cevent.dll). This file can be found in the new RMMerge tool which is installed with the RealVideo Encoder 4.0 beta.

RMMerge.exe, in conjunction with the rmevents.dll, replaces the old cevents.exe or cevent32.dll files.

For more information regarding the RMMerge tool, please see the RealVideo Encoder 4.0 beta release notes located in the Technical Support Library at:

Question: When playing an RA file with the Player, I get "Error 19: An error occurred while trying to connect to the RealAudio Server"

Solution:
If you receive the error message, "Error 19: An error occurred while trying to connect to the RealAudio Server", while trying to play an RA file with the RealAudio 2.0 or 3.0 Player, one of the causes is that your computer is probably behind a firewall. Other reasons are listed at http://www.realaudio.com/help/errors/error19.html

RealAudio Player 3.0 and RealPlayer 4.0 automatically select the most efficient mode of network transport, Multicast, UDP, or TCP, by default. Either get the final release of the Player or try manually switching from UDP to TCP in the Preferences dialog box.

The following are instructions on switching to TCP only. Open the Player or Player Plus from the RAPlayer folder, from the menu items choose View, Preferences, Transport. Click on the radio button which reads "Use Specified Transports", choose the button, "Specify Transports", click on "Attempt to Use TCP for all content" so there is an X in it. Click on the OK button at the bottom of the Preferences dialog box. Then play a file over the Internet. If this does not work, contact your System Administrator or ISP to create a proxy.

Question: Why do I receive no sound, various errors or continuous buffered play when trying to play RA, RM, or RAM files remotely on the Internet?

Solution:
Because you were unable to obtain audio or video content from the Player, I ran a tracert test of your Domain name to verify if you have a clear connection to the Internet. This test demonstrated your computer appears to be protected by a security system, called a firewall, which is why the Player is unable to make a connection.

To test this yourself , you should first determine whether or not the Player can play a local RA or RM file, such as thankyou.ra or thankyou.rm, which was copied to the system's hard drive when the Player was installed.

In order to play this file:

1. Open your RealAudio Player or RealPlayer.
2. Select Open File from the File menu.
3. Locate the RealAudio or Real directory on the hard drive.
4. Locate the thankyou.ra or thankyou.rm file.
5. Select the file and choose Open.

If you can play this local .RA or .RM clip from the local hard drive without an error, but when you attempt to play a remote file across the Internet, you hear no sound, or you receive error messages such as :

Error 1
Error 18
Error 19
Error 22
Error 26
Error 29
Error 30
Error 46
Error 47
Error 49
Error 86
Error 90
Error 107
Error 110
Error 111
Error 112
Buffered Play
a message regarding HTTP

This demonstrates that your computer is behind a security system, called a firewall. To resolve this, please contact your Internet Service Provider, ISP, or Network Administrator to obtain a proxy setting which you can use to configure your Player to access RealAudio and/or RealVideo content.

To configure the RealPlayer for a proxy setting:

1. Open the Player.
2. Select "Preferences" under the View Menu. For Mac versions of the Player, Preferences is located in the Edit Menu.
3. From the Preferences dialog box, select the "Proxy" tab.
4. Enter the information provided by your ISP for either the RealPlayer Proxy or HTTP Proxy.
5. Click "OK".

For more information about firewalls, see the firewall pages at:

http://www.real.com/help/firewall/user.html

You may receive an error for other reasons, for more information on the error, see the error pages at:

http://www.real.com/help/errors/index.html

Question: I receive an Error 18: Invalid Socket error, when I attempt to play an RA/RM file with RealPlayer or RealPlayer Plus 4.0.

Solution:
If you receive Error 18: "Invalid socket error" when attempting to play a RA/RM file over the Internet using the RealPlayer or RealPlayer Plus 4.0, it is likely that the system you are using is behind a firewall.

In order to determine whether or not the system is behind a firewall, you should first determine whether or not RealPlayer can play a local RA or RM file. One such file is thankyou.rm, which was copied to the system's hard drive when RealPlayer was installed.

In order to play this file:

1. Open your RealPlayer.
2. Select Open File from the File menu.
3. Locate the Real directory on the hard drive.
4. Locate the thankyou.rm file.
5. Select the file and choose Open.

If you can play this local .RM clip from the local hard drive without an error, it demonstrates that this error is most likely due to a networking firewall.

To resolve this error, set the proxy setting in the RealPlayer. The first step in doing this is to get a proxy setting. If you are using an ISP, or Internet Service Provider, to connect to the Internet, you can get this value from them.

To configure the RealPlayer for a proxy setting:

1. Open RealPlayer
2. Select "Preferences" under the View Menu. For Mac versions of the Player, Preferences is located in the Edit Menu.
3. From the Preferences dialog box, select the "Proxy" tab.

Product: RealAudio Player 3.0

Question: What are the steps to install the 3.0 UNIX Player?

Solution:
In order to download, install and test the RealAudio Player 3.0 for UNIX, please see the following instructions:

1. Download the RealAudio Player.

From the RealAudio Web site click Download RealAudio Player 3.0 and follow the
instructions for downloading the Player. Typically, you should download the Player to
your home directory.

2. Decompress and untar the downloaded file.

A. Change directories to the directory that contains the downloaded file.

B. To display the filename of the downloaded file, type:

ls

C. Type the following command:

zcat filename | tar xvf -

where filename is the name of the downloaded file.

The above command decompresses the file and creates a directory called
raPlayer3.0 that contains the following files:

raPlayer
RealAudio Player executable
README.FIRST
installation and usage document
LICENSE
license agreement
Mime.types
setup file for the web browser
Mailcap
setup file for the helper apps
raPlayer.ad
RealAudio Player application resource file
welcome.ra
RealAudio IDSN Stereo .ra file


3. Play the RealAudio welcome message by typing the following command from the
raPlayer3.0 directory:

raPlayer welcome.ra

4. Verify your Player's ability to access a file over the Internet, by clicking Open Location
from the File menu and enter the example URL given in the dialog box. Click the OK
button. The Player should connect to the server and begin playing.

5. Add the RealAudio Player to your path:

A. If you are using the csh or tsch shell, add the following command to your .cshrc
file after all other "set path" commands:

set path=($path $HOME/raPlayer3.0)

B. If you are using the ksh, bash, or bsh shell, add the following command to your
.profile file after all other "PATH" commands:

PATH=$PATH":$HOME/raPlayer3.0"

6. Verify that the path is setup correctly, type the following command from your home
directory:

which raPlayer

The directory where you installed the RealAudio Player should be displayed. If this
does not work, consult your system administrator for help in setting up your path.

7. Configure your web browser to use RealAudio Player when you click a RealAudio link.

Netscape 2.0

A. If you are not already in the raPlayer3.0 directory, change directories to
that directory.

B. Type the following commands:

cat Mailcap >> $HOME/.mailcap
cat Mime.types >> $HOME/.mime.types

C. Make sure that your web browser points to your .mailcap and
.mime.types files.

D. In Netscape, choose General Preferences from the Options menu. Then
choose Helpers.

E. The Personal Types File box should contain the directory location of your
.mime.types file. The Personal Mailcap File box should contain the
directory location of your .mailcap file. These files are typically located in
your home directory.

Netscape 3.0
A. In Netscape, choose Preferences from the Options menu. Then choose
Helpers.

B. Click the New... button. A dialog box appears.

C. Enter the following information at the appropriate prompt:

Description: RealAudio Player 3.0
Type: audio/x-pn-realaudio
Suffix: .ra, .ram

Handle by: check the Application box and enter: raPlayer %s

D. Save the new Helper information and exit the dialog box.

Mosaic

The Mosaic browser searches for the .mime.types and .mailcap files in your
home directory. For details, see Mosaic documentation.

8. Verify that the browser is configured correctly by clicking the home button (located on
the far right hand side of the Player above the volume slider) on the Player. This
displays the RealAudio home page on your default browser. Now click any RealAudio link, such as the NPR Morning Edition URL.

9. Make sure that your web browser is included in your path.

A. If you have a Netscape browser, type:

netscape &

If you have a Mosaic browser, type:

mosaic &

Your web browser should start.

B. If your web browser doesn't start, add the browser to your path.

10. Log out of your desktop and log in again. This ensures that all applications on the
desktop will be aware of the raPlayer directory that you just added to your path.

Question: How do I do a "clean install" of the MacOS based Player or Player Plus to verify correct installation of the Player?

Solution:
Performing a clean install removes any old components of the Mac version of the RealPlayer from your system, including the Player's preferences file. This will help verify that your Player is correctly installed and eliminate possible errors due to older libraries, and other components in use.

To delete all Player components from your Macintosh, perform the following steps:
1. From the desktop Finder menu, select File, then select Find File
2. Within the Find File dialog box, under 'Find files on local disks whose names contain __" type the word "real"', click Find.
3. Select all the files that appear by pressing the "command (Apple)" and "a" keys.
4. Verify that no files selected are personal files with the word "real" in them. To deselect those you wish to keep, hold down the shift key as you select them.
5. If you wish to keep the Player Installer you already downloaded, hold down the shift key and deselect the Player Installer by clicking on it from the list of files.
6. Drag all of the files to the trash.
7. You can empty the trash at this point if you like.

To reinstall the Player, restart your computer with only the System 7.x Extensions. To verify you are using these system extensions:
1. From the Apple Menu, select the Control Panel.
2. Select the Extension Manager.
2. If you are using a custom extension set, name the current set of extensions you are using. To do this, select "Save Set" from the drop down "Set" menu and assign them a name.
3. Select "System 7.x" from the "Sets" drop down menu.
4. Restart your Macintosh.

This will temporarily disable non-essential extensions which may conflict with software installation. The system will now have only the standard set of Apple's features and extensions turned on, including Internet connectivity. This enables the Player installer to complete the part of the installation procedure which takes you to content on the Internet.

Once you have restarted with System 7.x Extensions only, run the Player installer. After you have finished successfully you may wish to rebuild your desktop file.

Apple recommends that you rebuild the desktop file after you install new software. To rebuild the desktop file, hold down the "Command" and "Option" keys while you restart the computer. Keep the keys held down until you see an alert reading "Are you sure you want to rebuild the desktop file on the disk "nameofhardrive"?" Release the keys and click "OK". This process may take several minutes.

If you wish to return to the custom set of extensions you were using before you installed the Player, select your saved custom Extension Set in the Extension Manager.

Should installing the Player present difficulties, please provide more detailed information to Progressive Networks Technical Support Engineers at:

Question: Receive "Cannot launch setup.pif" message when launching RealAudio 2.0, 3.0, or RealPlayer 4.0 installer

Solution:
If you receive the error "Cannot launch setup.pif. Archive file corrupted, or possible download error. Please redownload this file or contact your system administrator", this is a notification from the decompression software that the file has become corrupt or did not download completely. There are several possible causes for this error.

Download problems can be caused by anti-virus software, screensavers, or other memory-resident software. When attempting to download or install the Player, you should temporary disable these programs.

When attempting to download the Player, if your system becomes disconnected during the download process, this is most likely related to network congestion. If your system becomes disconnected more than a couple times, wait until the Internet is less active and attempt the download at another hour of the day. The cause, however, could be that the connection to your ISP (Internet Service Provider) may not be stable, and in that case contact them directly to resolve this issue.

If you are experiencing difficulty downloading the Player or Player Plus installer to your hard drive try the following steps:

1. Temporarily disable anything you may have running in the background which may be causing a disconnection, such as anti-virus software or screensavers.

Software running in the background can be disabled though the following means:

Move applications listed in your Startup folders to another folder, and restart the computer.

Remark out any unnecessary applications listed in your autoexec.bat, and restart the computer.

2. Then, using the context sensitive menu, save the Player or PlayerPlus installer to your hard drive.

To do this:

Right mouse click on the download location and choose "Save Link As" from the menu items which appear, and save the Player installer to your hard drive.

If downloading continues to present difficulty, please contact technical support from the following Web site:

Question: I receive "expired" message after reinstalling it with a fresh download of the RealPlayer 4.0 or RealPlayer Plus 4.0 version.

Solution:
If your version of the RealPlayer or Player Plus 4.0 continues to give you a message that the version has expired after you reinstall it, this may be due to a variety of causes. To remedy this error, manually uninstall the Player software and all related files, and then install the most current version of the RealPlayer 4.01 or RealPlayer Plus 4.01.

If you are using Player Plus, be sure to locate your serial number before starting this process. You will need it to reinstall. This number can be found on the back of the CD case, if you purchased the boxed product, in the About dialog box, found off of the Help menu, of later versions of Player Plus, or in the confirmation e-mail Progressive Networks sent after you purchased the product on-line.

Question: When attempting to install the Irix version of RealAudio, I cannot uncompress the Irix installer.

Solution:
If you cannot uncompress the Installer for the IRIX version of the RealAudio Player, verify you have 'zcat' installed or use the "uncompress" command.

The IRIX RealAudio Player 3.0 installation program uses a command called 'zcat' to decompress the downloaded file. If your system does not have 'zcat' installed, you can also use the 'uncompress' command.

If you are still unsuccessful using either of these commands, verify that the file has not become corrupted during download.

In order to verify that the file is not corrupted, enter the following command:

sum v30_irix53.tar.Z

The file name within this command should match the name of the file that you downloaded. This command computes a checksum on the file. You should get these numbers if the file has not been corrupted during download:

46485 1585 v30_irix53.tar.Z

If the above number do not match, please download a new copy of the file and try again.

Question: I installed RealPlayer/Player Plus 4.0 on Windows 95/NT and but when I Iaunch the Player, it runs version 2.1 of the RealAudio Player.

Solution:
During the installation of the RealPlayer/Player Plus 4.0 on Windows 95/NT, you requested RealAudio to be uninstalled, but when you chose the RealAudio shortcut on the taskbar the 2.1 RealAudio Player runs instead. This usually indicates that you have Microsoft's Internet Explorer 3.0 or above on your system, which came with version 2.1 of the RealAudio Player. This version of the Player may not have been removed when you installed the RealPlayer 4.0.

These symptoms can occur after you receive the Windows 95 error, "The item "raPlayer.exe" that this shortcut refers to has been changed or moved". When you click OK, Windows 95/NT maps the shortcut to the older 2.1 version of the RealAudio Player. When you use the shortcut, it runs the older version of the Real Audio Player instead of the new RealPlayer 4.0. To resolve this, remove the old shortcut and create a new one that maps to RealPlayer 4.0.

To remove the old shortcut from the taskbar,

1. Right mouse click on a blank space taskbar on the Win95 desktop
2. Select "Properties" from the menu list
3. Open the "Start Menu", then Click on the "Programs" tab
4. Click on the "Remove" button
5. Locate the "RealAudio shortcut", and select it
6. Click on "Remove"
7. Click on "Close"

To create a new shortcut that points to RealPlayer 4.0, follow these steps:

1. Select the "Start" menu, Click on "Programs" menu item, choose Windows Explorer.
2. Locate the "Real" Folder, within this folder, select the "Player" folder.
3. Click on the "RVPlayer.exe" file.
4. Select the "File" menu. Select "Create shortcut".
5. Select the newly created Shortcut by clicking on it.
6. Drag and drop the "shortcut" onto the "Start Button" or "Desktop".

The shortcut is now mapped to the RealPlayer 4.0.

Have fun using the RealPlayer!

Question: Why am I getting an Error type 1 when I try to install the RealPlayer 4.0 for Macintosh Power PC?

Solution:
An early release of the RealPlayer 4.0 and RealPlayer Plus 4.0 versions for the Macintosh Power PC had an installation bug which generated an Error Type 1 on some systems, regardless of the method used to install the Player.

The cause of this behavior was found, fixed, and an new version of the Player, RealPlayer 4.1, put on our download site.

Question: Netscape Navigator 4.0 saves RA, RM, or RAM file, but does not launch the RealPlayer or RealPlayer Plus 4.0 and play the clip.

Solution:
Occasionally the Netscape 4.0 browser may not be configured properly after downloading and installing the RealPlayer or RealPlayer Plus 4.0 version. Netscape will prompt you for a location to save the .ra, .rm or .ram file rather than launching the RealPlayer/RealPlayer Plus 4.0 and playing the requested file.

This generally occurs due to a security warning that is generated by Netscape Navigator the first time that you request a .ra, .rm or .ram file. The first time Navigator attempts to play a RealAudio or RealVideo clip, Navigator launches a dialog box asking if you wish to "Launch the Application" or " Save the File". If you select "Save", Navigator will override the RealPlayer configuration and will not launch the RealPlayer, but will save the file instead. In order to resolve this issue, you will need to manually configure Netscape Navigator to launch the RealPlayer.

To configure the Windows version of Netscape Navigator to use the RealPlayer 4.0, verify that Navigator's settings match the following:

1. Start Netscape Navigator.
2. From the Edit menu, select "Preferences".
3. Within the Category windows, click on "Navigator". Navigator should have a minus - sign next to it
4. Click on Applications. To the right, the Applications window will appear.
5. Scroll down to see if "RvPlayer file" is listed.
6. If it is listed, it will be registered as:

Extension: RA RM RAM
MIME Type: audio/pn-realaudio
Handled By: RVPLAYER

7. Click on the Edit button. The "Edit Type" windows will appear.
8. Click on the "Handled by Application" radio button.
9. Locate the directory in which the RealPlayer was installed (default is c:\Real\Player) and select RVPLAYER.EXE as the application to launch, if the path is not already in the Application box.

Netscape should now be configured to launch the Player.

If RvPlayer is not listed, reinstalling the Player should configure Netscape Navigator to recognize RealPlayer.

To test that Netscape is now configured to launch the RealPlayer, go to your favorite RealPlayer site and double-click on a RA, RM, or RAM file. To locate new files to play, please visit the following Web site: :

http://www.real.com/welcome/

To verify the MacOS version of Netscape Navigator 4.0 is configured to launch RealPlayer, do the following:

1. Start Netscape Navigator
2. From the Edit menu, select "Preferences".
3. Within the Category windows, click on "Navigator".
4. Click on "Applications". The "Applications" windows will appear to the right.
5. Specify "Helper Application for different file type" under Application. You should see RealAudio RealPlayer.
6. Select "RealAudio RealPlayer"
7. Select "Edit".
8. If it is listed, it will be registered as:

Description RealAudio
Mime type audio/x-pn-realaudio
Suffix ra, rm, ram

9. Under "handled by", verify that the radio button next to "application" is selected. The application should be RealPlayer.
10. Select PNst under file type.

Reinstall the RealPlayer or Player Plus if these items do not appear in the Application configuration setting for the MacOS version of Netscape Navigator 4.0.

Question: Every time I attempt to download the Player, the download fails; is there a workaround?

Solution:
There are four main reasons why you may experience difficulty downloading an installer file from our site, or other sites on the Internet. They are Internet network congestion, connection to ISP is not stable, other applications running in the background, or CGI error.

These causes and work-arounds are detailed in the information below.

Internet network congestion may cause a disconnect while downloading the installation file., Another symptom of this problem is a corrupted file, which would give the following symptoms when you attempt to run them, an error that reads, "Cannot launch setup.pif. Archive file corrupted, possible download error. Please re-download this file or contact your system administrator" or some other similar message. The best solution in this case is to simply wait until the network congestion goes away. Since this problem occurs at peak usage times, success normally occurs at low demand hours, such as 9 p.m. or later in the evening.

If your system is disconnected frequently at various sites, the connection to your Internet Service Provider, ISP may not be stable. You should contact your ISP's support team regarding stability problems or review support materials on their site.

Downloads problems may be caused by other software running at the time of the download. This can include programs that you may have minimized, like a word-processing program, to anti-virus software, screensavers, or other memory-resident software that starts automatically when the computer is started. You should temporary disable these programs before downloading or installing the RealAudio Player or RealPlayer programs.

Software running in the background can be disabled by moving the applications listed in the Startup folders to another folder, and then restarting the computer. This applies to both the MacOS and Windows operating system, though the process is slightly different.

On a Mac,

1. From the Apple Menu
2. Select the Control Panel
3. Select the Extension Manager
4. From the Sets drop down menu , choose the System set, such as 7.5.5.
5. Then restart the machine.
6. Setting the Extension manager to the System Set maintains network connectivity, but disables non-standard extensions.

In Windows,

1. Open a text editor
2. Locate and make a backup copy of your Autoexec.bat file
3. Open the Autoexec.bat
4. Remark out memory resident applications, such a screensavers and anti-virus software listed in your autoexec.bat, by typing the letters REM in front of the application listing
5. Save the Autoexec.bat file.
6. Restart the computer.

When you are finished installing, be sure and reestablish your memory resident software, such as the returning your startup items to the Startup folder.

A CGI error is normally caused when an older browser is used in attempting a download from our site. If you encounter this rare error, you can resolve it by updating your web browser software. If possible, use a new release of the browser you prefer, but not a beta or pre-release version, to download the Player software..

Finally, if the above do not help you, try using the context sensitive menu item "Save File As" or "Save Link As". This is a helpful method when downloading a file is difficult. To do this on Windows 95 and NT, right mouse click on the download location and choose "Save Link As" from the menu items which appear, and save the Player installer to your hard drive. On a Mac, hold the mouse down for longer then usual and a menu will appear. From this menu choose "Save This Link As" and save the Player installer to your hard drive.

If downloading continues to present difficulty, please let our technical support engineers know the details via a support request located at: http://service.real.com/kb/

Product: RealAudio Player 3.0

Question: When I try to play a CD using the RealAudio Player in Windows 95, I receive Error 11: "This document is not a Realaudio document".

Solution:
If you attempt to play an audio file from an Audio CD, file type "CDA", using the RealAudio Player or Player Plus, you will receive and Error 11: "This document is not a RealAudio document".

It is possible to open the RealAudio Player on a Windows 95 based computer, and under the "File" menu, choose "Open File". By selecting the CD ROM Drive and under "Files of Type", choose "All Files", you will be able to see the listing of *.CDA files. While you can see these files within the Player dialog, you will not be able to play them. You will receive
Error 11: "This document is not a Realaudio document."

The RealAudio Player is designed to play .ra and .ram files across the Internet or from your local harddrive. On the web, RealAudio files are usually identified by a RealAudio bubble Icon, RealAudio logo or other indicators of a RealAudio file, such as an image or text. On some web sites RealAudio files play automatically using plug-ins embedded with your browser. The RealAudio Player is not designed to play "CDA" files from a Compact Disk.

On Windows 95, if the CD does not play automatically, using the built in CD Player, insert the CD into the CD Player and complete the following steps:

1. From Start button, select "Programs".
2. From "Programs", select "Accessories".
3. From "Accessories", select "Multimedia".
4. From "Multimedia", select the "CD Player".

The options on the CD Player work very much like a regular CD Player, with buttons for such functions as play and stop. You should be able to click on the "Play" button to begin playing the CD.

If this does not work, or you do not find the CD Player, you may have accidentally uninstalled it and you may need to contact Microsoft Windows Technical Support for assistance.

Question: After installing the 16-bit RealAudio Player 3.0 on Windows NT, I get Error 41: Requested RealAudio Decoder cannot be found or cannot be used on this machine.

Solution:
After installing the 16-bit version of RealAudio Player 3.0 on Windows NT 3.5 or 4.0, you may receive Error #41: Requested RealAudio Decoder cannot be found or cannot be used on this machine.

Windows NT does not support the Windows 3.1 (16-bit version) of the 3.0 Player. To use the 3.0 Player or Player Plus on Windows NT, you will need to obtain the 32-bit Windows 95/NT RealAudio Player, as well as a 32-bit winsock and browser.

The RealAudio Player can be downloaded from the following URL:

http://www.realaudio.com/products/Player/download.html.

If you purchased the Player Plus CD, you can install the Windows 95/NT version from the CD.

Although some ISPs still only provide 16-bit winsocks and browsers, most ISPs will assist their customers in upgrading to a 32-bit winsock, browser and dialer. Many ISPs provide information about 32-bit upgrades on their help pages.

Product: RA Encoder 3.0

Question: Using the Encoder, I get an error, "Cannot convert source audio data for the compression chosen".

Solution:
When using the 3.0 Encoder, I get the error "cannot convert source audio data for the compression chosen".

The RealAudio Encoder cannot convert audio files which are already compressed. Verify that the format of the file you are trying to convert is what you expect.

For more information regarding supported input file formats, please see the following URL:

http://www.real.com/help/encoder/win3.0/

Select the hypertext link for "Supported Input File Formats" in the left frame.

The Encoder does not support compressed variants of the formats described above. Use a sound editing utility to convert it to a supported format. The RealAudio Encoder creates a compressed audio format, and cannot use compressed audio formats.

Product: RA Encoder 3.0

Question: I am getting a warble in my RealAudio file I encoded. How do you improve sound quality of RealAudio Encoded files?

Solution:
When encoding RealAudio files at lower bit rates, you may experience a warbling or "underwater" effect in your files. At low bit rates, some artifacts are unavoidable. By normalizing the file (by sending the encoder a nice, loud signal), you can usually improve the sound quality, however, the file will still have some undesirable background noise. This is included in the tradeoff for the massive amount of data reduction.

Please see http://www.realaudio.com/help/FAQ/ for tips on improving sound quality.

For information about producing the best quality RealAudio files, see our Audio Hints page at:

http://www.real.com/help/content/audiohints.html

Product: RealVideo Encoder 4.0

Question: Are there better codecs for voice recordings in RealVideo Encoder 1.0 than found in RealAudio 3.0 Encoder?

Solution:
Progressive Networks has designed two new codecs for the RealVideo Encoder 1.0 specifically for voice. They are the 6.5 and 8.5 Kbit voice codecs.

Voice codecs are not responsive when encoding at the high end, because they are designed with the mid-range frequency of the human voice in mind.

For a wider frequency response, such as with music recordings, use one of the 16 k music codecs.

Product: RA Encoder 3.0

Question: Is it possible to convert an existing RA file to a different RA format and rename it?

Solution:
It is not possible to directly convert one RA file to another RA format- such as converting a 28.8 file to a 14.4 file. Once encoded, the RA files become compressed and cannot be converted to another compressed file. If the compression is attempted, distortion and other problems will occur.

In order to encode the audio clip in another RA algorithm, you need to encode the file in the format you desire, using the original digital sound file and the RealAudio Encoder.

Product: RealAudio Player 2.0

Question: My connection is faster than 28.8 Kbps, so why does the Player indicate it is playing at 28.8 Kbps?

Solution:
Many users have connections that have greater throughput than 28.8 Kbps, but the RealAudio Player 2.0 never indicates anything greater than that rate. The reason for this are the algorithms used to encode RA files.

The RealAudio Encoder which is used to make RealAudio clips supports two encoding algorithms, 14.4 Kbps and 28.8 Kbps. Regardless of the type of connection, such as ISDN, T1 or T3 line, the RealAudio Player will only display a 14.4 Kbps network stream, a 28.8 Kbps network stream or live play through. Simply, the RealAudio Player is receiving the file in the algorithm the clip was recorded in.

Question: "Error 28, server timed out. Server not responding", when running RealAudio Player on a Macintosh

Solution:
When playing a RealAudio file on an Apple Macintosh and you receive a message "Error 28, server timed out. Server not responding", verify that you have the most current version of the RealAudio Player. For the Macintosh, this is currently v. 3.0. To check the version when running the RealAudio Player, choose About RealAudio from the Apple menu. Also verify that the Apple Sound System Control Panel is configured correctly.

Try these steps to get your system configured properly:

1. Trash the RealAudio folder found inside the System folder within the Extensions folder.
2. Use the Find command from the File menu in the Finder, search the hard drive for RealAudio and delete any other folders of the same name.
3. Download the RealAudio Player from our website: http://www.realaudio.com/products/Player.html#download
4. Install the Player.
5. Verify that you have the most current version of the Sound Control Panel.
6. Verify that Playthrough is selected in the Sound Control Panel. From the Apple Menu item choose Control Panels, Sound, Sound In, and from the Options dialog box select the Playthrough box, place an X in the box.
7. Turn off the "Network Software Selector' Control Panel that came with the Apple System update 7.5.3.

Please note: If you need MacTCP for older applications, Apple has provided a "Network Software Selector" Control Panel item; verify that OT (Open Transport) is selected when using RealAudio. If you do not need Mac TCP, you can remove both the Macintosh Control panel and the Network Software Selector.

Question: Why are RealAudio keys and values put under Software in the root key in the registry for Windows '95/NT?

Solution:
RealAudio Player 2.0 installs it's keys and values under Software (OLE Part 2 of 5) in the root key as opposed to under HKEY_LOCAL_MACHINE/Software or HKEY_CURRENT_USER/Software. This is done so that 16-bit and 32-bit versions of the RealAudio Player can access the same preference settings.

16-bit EXE's cannot read the HKEY_LOCAL_MACHINE and HKEY_LOCAL_MACHINE sections of the registry. In order to allow systems with 16-bit and 32-bit RealAudio applications installed to use the same proxy, network and audio settings, we have chosen to use the HKEY_CLASSES_ROOT section.

Question: Why is there hissing when I play a RA clip?

Solution:
Hissing may occur if your system's speakers are not grounded, or if another electrical cord is causing interference with the speaker's cables.

To determine if hardware is at fault, try playing a different audio file, such as a WAV or a MIDI file. If the hissing persists, there is a hardware problem, i.e. speakers not grounded, electrical interference from another source. If the hissing does not go away, please contact us again, noting that you have already been in touch with us on this issue so we may further investigate the problem.

Question: Why do I hear a flutter when playing a RealAudio file while working on my computer?

Solution:
The RealAudio Player is a processor intensive application. If too many applications are requesting CPU time while the Player is receiving a stream, the sound will flutter a bit until the other processes are completed.

This is not to say that you cannot have other processes running while receiving streaming audio, but the more CPU intensive the processes are, and the more of them that are running simultaneously, the less processor time is available for the RealAudio Player to play a continuous stream of sound.

Question: How do I receive stereo sound on the RealAudio Player 3.0?

Solution:
To get stereo on RealAudio Player/Player Plus 3.0, you need a 28.8 Kbaud modem, a connection to a RealAudio 3.0 Server that is providing stereo content, for example the RA file has to be encoded as a stereo file. Verify that the bandwidth options in the Network tab of the Player's Preferences dialog box is set to 28.8 or better.

For samples of clips in stereo, please visit the RealAudio 3.0 Showcase located at:

Product: RealPlayer 4.0 beta, RealPlayer Plus 4.0 beta, PN Support

Question: RealPlayer 4.0 beta continues to rebuffer, although I don't seem to have any packet loss. What is happening?

Solution:
If you are experiencing rebuffering with RealPlayer 4.0 beta, and as a result the sound and/or picture quality is not clear, but you do not appear to be experiencing any packet loss, this may be due to low bit rates, or a slow connection speed. You may also receive errors about poor system performance.

Check the difference between what connection speed your ISP is providing you and what the requirements for file you are playing requires to be played clearly. You can do this in the Player menu items by going to View, Statistics, Details. Under bandwidth, the top option, "Clip" displays what bandwidth in bits per second (bps) the file requires and "Current" displays what bandwidth or connection rate your ISP is supplying you with.

The behavior that you are experiencing is generally caused by "thin" bandwidth, thus the Player can not support the file you are trying to play.

We recommend you contact your ISP or System Administrator regarding improving the quality of the connection in order to provide a consistent connection at a bandwidth capable of supporting the file format you expect to use. This should be based on the speed of the computer's CPU and the bit rate of the connection, such as a 28.8 modem or a direct network connection like a T1.

AUDIO ONLY:

For example: Using a 486/66 DX computer with a 28.8 modem, the RealPlayer 4.0 beta should be able to play an AUDIO ONLY "28.8 Mono, full response" through a 16.0 Kbps connection. If your modem displays less then this in the modem software, or it fluctuates below this then the Player will not be able to deliver clear, refined and continuous sound for this file format. Please see the table below for more information:

The following is the actual bit rate required to transmit each RealAudio codec:

RealAudio 2.0 - 14.4 8.0 Kbps
RealAudio 2.0 - 28.8 15.2 Kbps
RealAudio 3.0 - 28.8 Mono, full response 16.0 Kbps
RealAudio 3.0 - 28.8 Mono, medium response 16.0 Kbps
RealAudio 3.0 - 28.8 Mono, narrow response 16.0 Kbps
RealAudio 3.0 - 28.8 Stereo 20.0 Kbps
RealAudio 3.0 - ISDN Mono 40.0 Kbps
RealAudio 3.0 - ISDN Stereo 40.0 Kbps
RealAudio 3.0 - Dual ISDN Mono 80.0 Kbps
RealAudio 3.0 - Dual ISDN Stereo 80.0 Kbps

VIDEO:

For Example: Using a Pentium 75 computer with a 28.8 modem, the RealPlayer 4.0 beta should be able to play a VIDEO clip at "High Action 28.8 w/Voice" through a 19.0 Kbps connection. If your modem displays less then this in the modem software, or it fluctuates below this then the Player will not be able to deliver clear, refined and continuous sound and/or video picture for this file format.

Please see the table below for more information.

RealVideo (.RM) clips support several encoding algorithms:

High Action 56 w/Voice 90 Kbps
High Action 28.8 w/Music 19 Kbps
High Action 28.8 w/Voice 19 Kbps
High Action (Fractal) 45 Kbps
High Action 56 w/Music 45 Kbps
High Action 56 w/Voice 45 Kbps
Music Video 28.8, Emphasize Audio 19 Kbps
Music Video 28.8, Emphasize Video 19 Kbps

The RealPlayer 4.0 beta was designed to buffer in an attempt to improve the sound and picture quality of the file that is being played. This behavior is more likely to occur if the clip requires a transmission rate close to the actual connection speed.

There is no easy solution from within the Player to resolve buffering problems or loss of sound or picture quality. You can try connecting at a time when traffic on the Internet is lighter, upgrading to a faster modem, or switching to an ISP with less traffic.

You can also try setting your connection bandwidth to a higher setting that your actual bandwidth. In order to do this, please do the following:

1. Under the View menu, Select Preferences.
2. Select the Connection tab.
3. In this dialog, you will see a option for bandwidth. Set this option to a level higher than you actual connection. For example, if you have a 14.4 modem, set it to 28.8.
4. Select "OK".

As an alternative, you could set the Player to buffer the entire clip prior to playback.

Windows 95

In order to do this, change the following settings within the RealPlayer:

1. Open the RealPlayer.
2. Under the View Menu, Select "Preferences".
3. Within the Preferences dialog, Select the "General" tab.
4. Under "Perfect Play/Buffered Play", click the radial button for "Buffer entire clip up to available memory ".
5. Click "OK".

If you find you don't have enough memory to buffer the entire clip, you will need to change the buffering setting within the RealPlayer 4.0 beta to buffer only a portion of the clip, rather than buffering the entire clip.

1. Open the RealPlayer.
2. Under the View Menu, Select "Preferences".
3. Within the Preferences dialog, Select the "General" tab.
4. Under "Perfect Play/Buffered Play", click the radial button for "Buffer at least at least <60> seconds before playing". The seconds field is defaulted to 60 seconds. You can increase the figure depending on your available memory. If set to a value higher than the available memory, the Player will simply buffer as much as possible with the available memory.
5. Click "OK".

Macintosh Power PC

In order to do this, change the following settings within the RealPlayer:

1. Open the RealPlayer.
2. Under the Edit Menu, Select "Preferences".
3. Within the Preferences dialog, Select the "General" tab.
4. Under "Perfect Play/Buffered Play", click the radial button for "Buffer entire clip up to available memory ".
5. Click "OK".

If you find you don't have enough memory to buffer the entire clip, you will need to change the buffering setting within the RealPlayer Plus 4.0 beta to buffer only a portion of the clip, rather than buffering the entire clip.

1. Open the RealPlayer.
2. Under the Edit Menu, Select "Preferences".
3. Within the Preferences dialog, Select the "General" tab.
4. Under "Perfect Play/Buffered Play", click the radial button for "Buffer at least at least <60> seconds before playing". The seconds field is defaulted to 60 seconds. You can increase the figure depending on your available memory. If set to a value higher than the available memory, the Player will simply buffer as much as possible with the available memory.
5. Click "OK".

Question: When playing a RealAudio/RealVideo file on the Windows 95 RealPlayer/Player Plus 4.0, I get "Error 19: An error occurred while trying to connect to the RealAudio Server".

Solution:
If you receive "Error 19: Error connecting to while trying to connect to the RealAudio Server" when playing an RA/RM/RAM file via the RealPlayer 4.0 for Windows 95 or Windows NT on a system using a 16-bit dialer or browser or winsock, the problem lies with a conflict between the 32-bit Player and the 16-bit winsock.

Other possible causes for this error are documented at:

http://www.real.com/help/errors/error19.html

If error 19 occurs every time you try to listen to a RA, RM or RAM file on any Web site, but you can play the welcome.ra file from your RealAudio or Real folder, your winsock needs to be updated.

To resolve this error, upgrade your winsock and browser to a 32-bit version. Please download and install the 32-bit browser and winsock from your ISP (Internet Service Provider's) web site. If you experience difficulties, contact your ISP for information on how to upgrade to a 32-bit version of winsock and browser.

Question: After increasing the memory on my Macintosh, I am continuing to receive Error 2: Out of Memory.

Solution:
If you are receiving "Error 2, Out of Memory" on a Macintosh, verify that the Sound options are set correctly in the Control Panel.

To verify the settings, please do the following:

1. Under the Apple Menu, select "Control Panels".
2. Within "Control Panels", select "Sound".
3. From the Pull Down menu, select "Sound In"
4. Click on the "Options" icon. A Dialog box will open.
5. Verify that the Options for "Play Through" and "Internal CD" are selected. If not, select the appropriate radio buttons.
5. Click OK.
6. From the Pull Down menu, select "Sound Out".
7. Verify that the rate is set to either 22.050 kHz, or 44.100 kHz
8. Close the Dialog.

There may be some bugs with the Sound control panel item on some versions of the Mac OS.

Deleting the Shared Library Manager preferences file (ASLM Preferences) also cures this behavior and will eliminate this error. The ASLM preferences file appears to affect all applications that try to load a shared library into memory.

In order to remove the ASLM Preference file from your Preferences folder, complete the following steps:

1. From the Macintosh Finder, go to the File menu, Choose Find.
2. Under "Find items on local disks whose name contains", type in "ASLM"
3. Click on Find.
4. Under items found, you will see a file called ASLM Preferences, located in the System Folder, within the Preferences folder.
5. Drag the ASLM preferences to the trash and empty the trash.
6. Restart the Mac.

The Mac OS will build a new ASLM file after you restart the machine.

Question: When using RealAudio Player 3.0, I receive Error 53: "Invalid host string in requested URL."

Solution:
"Error 53: Invalid host string in requested URL. when attempting to play a RA file across the Internet" occurs in the RealAudio Player version 3.0 for several reasons. One is that your network has a firewall and the Player needs to be configured to use a proxy, and the other is an incorrect URL was entered into the Open Location feature of the Player.

If you receive this error, and you are on a network that has a firewall, you may need to configure a proxy in order to receive RealAudio. A proxy acts as a go-between for a firewall and a network. If you are behind a firewall, you need to contact your Network Administrator or ISP to obtain a proxy which you can configure.

To configure your RA Player for a proxy, see the steps below:

1. Open the RealAudio Player.
2. From the View Menu, Select "Preferences".
3. From the "Preferences" window, click on the "Proxy Tab".
4. Click on the "Use Proxy" option.
5. If your network has a RealAudio Proxy, fill in the appropriate details and port number.*
6. If your network uses a HTTP Proxy, fill in the appropriate details and port number.*
7. Click "OK".

*If you are unsure of these settings, please contact your Network or System Administrator.

You may also receive an Error 53 if you use the Open Location option from the File Menu in RA Player or Player Plus and type in an incorrect or incomplete URL, such as:

http://www.realaudio.com

RealAudio files usually end in an .RA or .RAM extension, therefore an example of a valid URL is:

pnm://audio.realaudio.com/welcome.ra

Question: When I play a RealAudio file with the 3.0 Player or Player Plus I get "Error 29: Server Disconnected", followed by "Error 19: An error occurred while trying to connect to the RealAudio Server"

Solution:
When using the 16-bit 3.0 RealAudio Player or Player Plus with a 16-bit winsock, you may encounter "Error 29: Server Disconnected", followed by "Error 19: An error occurred while trying to connect to the RealAudio Server"

This occurs when 16-bit RealAudio Player does not autoswitch from UDP to TCP when the Player has trouble receiving UDP packets. To resolve this, configure the Player so it uses TCP instead of UDP for transport.

This can be done by following these steps:

1. Open the Player or Player Plus from the RAPlayer folder
2. From the menu items choose View, Preferences, Transport.
3. Click on the button which reads "Use Specified Transports",
4. Choose the button, "Specify Transports",
5. Click on "Attempt to Use TCP for all content" so there is an X in it.
6. Click on the OK button in the "Specify Transports" dialog box.
7. Click on the OK button in the "Preferences" dialog box.

The Player is now ready to go.

Please reply to this email, sending it back to PN Technical Support if this does not help solve this problem.

Question: When attempting to play a RealAudio file using the Open Location option within the RealAudio Player/RealPlayer, I receive Error 54: "Invalid resource path string in requested URL".

Solution:
If you receive "Error 54: Invalid resource path string in requested URL" when attempting play a RA file using the "Open Location" feature within the RealAudio Player/RealPlayer, verify that the URL address extension you are attempting to play ends in a .RA, or .RAM.

For example, if you use the RealAudio Player menu item "Open Location" and enter the following:

pnm://www.realaudio.com

and click OK, you will receive an Error 54. This URL is incomplete. The address must contain the name of the .ra file.

However, if you enter the following address:

pnm://audio.realaudio.com/welcome.ra

The RealAudio file at that URL will play without an error.

The "Open Location" menu feature requires very specific syntax and punctuation. Verify the exact address of the RealAudio file to prevent receiving errors.

For more information about the "Open Location" menu item within RealAudio Player/RealPlayer, please see the RealAudio 3.0 or RealPlayer 4.0 Release notes located in the Technical Support library at:

Question: Getting Error 30, cannot resolve the requested network address

Solution:
This error indicates that the RealAudio Player is attempting to resolve the RealAudio Server's Internet (IP) address by accessing the Domain Name Server (DNS), a database with a dotted-quad number corresponding to the domain name, and not succeeding.

There are several reasons why an IP address cannot be resolved. One is if the name is typed wrong in a .RAM file, or incorrectly entered in to the Player's location window. Another is if the ISP is not configured to access an appropriate DNS server.

IP addressing is a hardware independent scheme, achieved by assigning each host a unique 32-bit number, called the IP address; usually written as four decimal numbers, one for each 8-bit portion, separated by dots, it is also called dotted quad notation. If a name which corresponds to the dotted quad is typed in wrong or the ISP is not configured correctly the error 30 occurs.

To solve this, verify that the syntax of the address is correct. If it is, please contact your System Administrator for additional assistance.

Question: I received Error 105: "DNS looked out timed out" from the RealPlayer or RealPlayer Plus 4.0x when playing an RA or RM file.

Solution:
If you received Error 105: "TCP connection to the server timed out.." when attempting to play a .ra or .rm file using the RealPlayer 4.0x, or RealPlayer Plus 4.0x, this means the attempt to connect to the TCP server took longer than allowed. This problem can be caused by a high network load, such as too much traffic on the Internet, or the content provider's server may be down.

If too many people are trying to connect to a given site, try again later, or increase the Player's wait time. This is changed by selecting the View menu, and then clicking on the Preferences menu item, which brings up the Preferences dialog box. From there, select the Connection tab, and then increase the Connection timeout value.

If the content provider's server is down, the only solution is to contact the server administrator of the site you are trying to access and let them know you are receiving this error from their site. Meanwhile, try other sites.

Question: I installed RealAudio and now my mouse does not work

Solution:
If, after installing the RealAudio Player, the system's mouse does not work, or works only intermittently, there is probably a conflict between the mouse driver and the sound card driver.

Using the manuals for the mouse and the sound card, verify the configuration for each of these components, making sure they are not set to the same interrupts or Direct Memory Access channels.

As part of this process, verify that you have the most current and up to date drivers for these devices that are also compatible with the operating system. This information is available by going to the Original Equipment Manufacturer's (OEM's) Web site, or by phoning them.

If you need additional assistance with this matter, you may want to contact a local repair shop or computer professional. This can be a difficult, time-consuming process problem to resolve.

Question: I installed RealPlayer 4.0 on Windows 95. However, when I attempt to use the shortcut, it prompts me to install again.

Solution:
During installation of RealPlayer 4.0 on Windows 95, you requested RealAudio to be uninstalled. However, when you chose the RealAudio shortcut on the taskbar the RealPlayer 4.0 installer runs in an infinite loop, or it runs another application.

This can occur after you receive a Windows 95 error reading "The item "raPlayer.exe" that this shortcut refers to has been changed or moved". When you click OK, Windows 95/NT maps the short cut to the RealPlayer installer (or some other executable). When you use then use the shortcut, it runs the installation program again.

This can be remedied by removing the shortcut and creating a new one.

To remove the old shortcut from the taskbar,
1. Right mouse click on a blank space taskbar on the Windows 95 desktop.
2. Select "Properties" from the menu list
3. From the "Start" Menu, select the "Programs" tab.
4. Click on the "Remove" button
5. Locate the "RealAudio" shortcut, and select it
6. Click on "Remove"
7. Click on "Close"

To create a new shortcut:

1. From the "Start" button, select the "Programs" menu, choose Windows Explorer.
2. Locate the "Real" Folder, Select the "Player" folder.
3. Click on the "RVPlayer.exe" file.
4. From the "File" menu, select "Create shortcut".
5. Select the "Icon" and drag and drop the shortcut on the "Start" button, "Desktop" or wherever you wish

This shortcut should launch the RealPlayer 4.0.

Have fun using the RealPlayer 4.0.

Question: I am receiving Stack Fault errors when using the RealAudio Player 3.0 on Windows 3.1.x

Solution:
If you are receiving stack errors when running the 3.0 RealAudio Player on Windows 3.1.x, this can be caused by several things:

1. Outdated sound card drivers
2. Conflict with a TSR, screensaver or anti-virus program
3. DLL conflicts with older version of RealAudio still installed on system.

The RealAudio 3.0 Player now includes several stereo codecs that utilize the latest sound card drivers. If you attempt to play a RealAudio file that utilizes these newer codecs with outdated sound card drivers, a stack fault will occur.

In order to correct this problem, we recommend the following:

1. Contact your sound card manufacturer to verify that you are using the latest sound card drivers. If not, update them.

If the problem does not appear to be outdated sound card drivers, we recommend you take the following steps:

1. Manually uninstall all versions of the RealAudio Player/Player Plus. If you have Player Plus, be sure to save your serial number. You will need it to reinstall Player Plus.

2. Run Scandisk and full Defrag to repair small file system errors on the hard drive. Scandisk and Defrag are two utilities provided by Microsoft in DOS 6.22.

3. Restart your computer with a minimal system configuration; disable any software running in the background. Remove all screensavers, anti-virus software and TSRs and any other programs found in startup folders.

These steps are detailed below:

1. Remove all files and directories copied to the system by previous installations:

In C:\RAPLAYER (or the directory specified during the installation):

RAPLAYER.EXE
README.HTM
NOTES.HTM
START.RAM
RA.GIF
BOOKMARK.SAV
THANKYOU.RA

In C:\WINDOWS

RAUN16.EXE

In C:\WINDOWS\SYSTEM directory:

RACT14_4.DLL
RA3228_8.DLL
RACTDNET.DLL
DECDNET.DLL
PNEN1630.DLL
PNUI1630.DLL
PNLOADER.DLL

In C:\WINDOWS\HELP directory:

RAPLAYER.HLP

If you installed the RealAudio Plug-In, then in the Plug-in directory of your browser:

NPRA16.DLL

2. Run SCANDISK, with maximum detection.
3. Run DEFRAG.
4. Download a new copy of the RealAudio Player.
5. Disable screensavers, virus scanning software, and temporarily move icons in the startup folder to another folder. Restart the computer.
6. Run the installer.

Question: When I try to play a RealAudio file on my Macintosh, a -609 or -1712 error occurs.

Solution:
hen an error box is displayed with error type -609 or -1712 on a Macintosh, this is the result of an Apple event timing out. To resolve the error, click the stop button on the RealAudio Player, and then press the Start button or, shut down the Player and the browser software and then restart both applications.

In some cases there is a software conflict between the Macintosh Operating System and one or more system extensions, INITs, that prevent the RealAudio Player from working correctly. Stopping the Player or turning off the browser will not resolve the errors in this case.

This can be fixed by disabling conflicting extensions with the Extensions Manager. To get to this, go to the Apple Menu under the Control Panel and choose the Extensions Manager.

If Extensions Manager is not listed in the Control Panel, open the system folder on the hard drive and look for Extensions Manager in the Control Panels Disabled folder, then move it to the Control Panels folder. It should now appear under the Control Panels folder in the Apple menu.

If the Extension Manager is set on Sets: Custom, choose Save a Set from the drop down menu item and save your custom set under any memorable name. Then, under Sets: choose System 7.5.x. Restart the machine and try playing a RA clip. Note that this will sustain network connectivity but will disable all non-Apple standard extensions.

Note that for best results with RealAudio on a Macintosh, PN suggests using system version 7.5.3 and Open Transport.

If these directions fails to prevent these errors from occurring, please reply directly to this mailing, including a detailed explanation of the steps you took to duplicate the error(s), and a list of all extensions in use in the System Extensions folder.

Question: I'm getting "Error 2: Out of memory" on Windows '95 when running RealAudio Player 3.0 or RealPlayer 4.0.

Solution:
"Error 2: Out of memory error", in the Windows '95 version of the 3.0 RealAudio Player or 4.0 RealPlayer is generally accurate. To provide more memory to Windows '95 try these steps:

1. Free some hard drive space, delete old files, empty the recycle bin, or move unneeded files to storage disks.
2. Uninstall all versions of the Player in the Windows, Control Panel, Add/Remove Software.
3. Run a (standard) Scandisk and a (full) Defrag from the Start Menu, Run menu item.
4. Check to see if you are or if Windows is handling the virtual memory in the control panel. Go to Start, Control Panel, double click on System, in System Properties click on the Performance tab, and then the Virtual Memory button in the lower right hand corner of the dialog box. If you are handling Windows 95's virtual memory, try increasing the memory.
5. Run fewer applications in the background by temporarily disabling screensavers or other applications, including virus scanning software.
6. Reinstall the Player if that's what you wish to use (pick up a new copy from the URL in your original confirmation email from Progressive when you first purchased Player Plus )

After making these changes, reboot the computer and try the Player again. If these steps do not help, please reply to this message, keeping the message thread intact, indicating the behavior you are now experiencing.

Question: Why do I receive the error message: bandwidth too narrow or CPU too slow when I try to play RealAudio files?

Solution:
You may receive an error message: bandwidth too narrow or CPU too slow when attempting to play 28.8 files over a 14.4 Kbaud modem. To overcome this error, manually change the RealAudio's Player bandwidth configuration from 14.4 to 28.8.

Do this by choosing the View menu, then the Preferences menu item. In the resulting Preferences dialog box, click on the Network tab, and then change the Bandwidth setting to 28.8 Modem.

With the files being transmitted at 14.4 Kbaud, you will probably note that 28.8 RA files are choppy in comparison to 14.4 RA files. 14.4 RA files will naturally stream more smoothly that 28.8 RA files through a 14.4 Kbaud connection.

Question: After installing RealAudio Player 3.0 for Macintosh, the Helper Application mime types are entered but not recognized by browser, will not install, or does not find application.

Solution:
When attempting to use the RealAudio Player 3.0 for Macintosh, if the Macintosh Desktop File (the internal database that keeps track of icons, aliases, and file locations) becomes corrupt, a number of symptoms may occur:

1. When trying to access a RealAudio link, a window comes up saying "..will open with the RealAudio Player." However, the Player does not come up and a alert window asks whether you would like to save or delete the file.

2. When installing the Player a message comes up which reads, "Could not open RA Player Installer (PPC)...sit after download, because application that created it could not be found..."

3. When trying to select a file type in the helper applications, TEXT is the only option.

4. The icon associated with the RealAudio Player in the helper applications is generic.

5. The downloaded .ram files appear without a RealAudio icon.

If any of these symptoms occur, the Macintosh Desktop file has become corrupted. To rebuild the Desktop File, restart your Mac and hold down the Option and Command keys until a message appears which asks if you wish to Rebuild the Desktop, click "OK".

Question: You recommend Open Transport to use with RealAudio and RealPlayer, how do I get it?

Solution:
Progressive Networks recommends using Open Transport and version 7.5.3 or greater of the Macintosh OS with the RealAudio Player and RealPlayer.

Open Transport 1.1 came with the update 2.0 for the Macintosh OS 7.5.2. This updated the Macintosh Operating System to 7.5.3, which, if MacTCP was installed, would install a program in the Apple Extras folder named Network Software Selector. Open Transport is intended as a replacement for MacTCP.

The new Network Software Selector allows you to switch between MacTCP and Open Transport to insure backward compatibility with older network applications. Your system does not need the Network Software Selector installed in the Control Panel, under the Apple Menu, to run RealAudio unless you need backwards compatibility with older applications.

To verify that your sound configuration is set correctly, under the Apple menu item, in the Sound Control Panel, under Sound In, Options, Internal CD is set to Playthrough (It has an X in the box).

Windows 95 has known problems when using older, outmoded video device drivers and S3 chipsets on video cards. If you are installing or using the 3.0 RealAudio Player and Windows 95 drops to DOS or locks up, please download and install the latest drivers from the manufacturer's website.

The S3 chip set is found on the following manufacturer's video cards: Matrox, Cirrus Logic, and Diamond (Stealth)

Many people upgrade from Windows 3.1 to Windows 95 or Windows NT and they do not realize they are using (legacy) real mode drivers, instead of the new virtual device drivers. A system upgraded from Windows 3.1 to Window 95 or Windows NT may even work fine for a while with the old video and sound drivers.

But when the system is taxed, the older drivers will not perform correctly. Symptoms are apparent during installation, when using multiple applications, or large applications which tax the video display drivers. Symptoms that can occur are:

· some parts of the image simply do not display.
· wavy lines on the video display, similar to what appears to be like television interference.
· computer system will lock up.

The common test for video drivers is, if it works okay with the Microsoft standard VGA driver and not with the one on the system, the problem is most likely the old driver.

Question: Will the RealAudio Player work with the OS/2 or Warp operating systems?

Solution:
The 16-bit versions of the RealAudio Player work on the OS/2 operating systems. Many users of OS/2 are curious about Progressive Networks' future plans of RealAudio as it relates to this operating system. Unfortunately, we have not created a native version of the Player for this operating system, nor do we have plans to do so.

Many OS/2 users have successfully installed and used the RealAudio Player on their systems. We have instructions on setting this up available on our Web site at: http://www.realaudio.com/help/FAQ/os2warp.html

The contents of that FAQ follow.

***********************************
RA Player FAQ for OS/2 Warp


You can run the Player in a WinOS/2 Window with a Windows Browser, though it can be difficult to install. We suggest the following steps:

1. Use the program Web Explorer Beta available from IBM URL www.teamos2.org/software/. Earlier versions may work also, but have not been tested.

2. In EXPLORE.INI set up the paths for MAILCAP and EXTMAP. Example for Web Explorer and TCPIP in D:TCPIP. Adjust accordingly.

[advanced]
; advanced user settings - edit with care!
; mailcap= specifies full path to user mailcap file
; format is: mime/type; program_name params %s
; example: image/jpeg; jview -r %s
; no wildcards allowed, no piping, no unix commands
mailcap=d:\tcpip\etc\mailcap.cap
; extmap= specifies full path to user extension map file
; format is: mime/type extension_list
; example: image/jpeg jpg jpeg jpe
extmap=d:\tcpip\etc\extmap.ext

3. In MAILCAP.CAP add the line:

audio/x-pn-realaudio; i:\raPlayer\rago.cmd %s

4. In EXTMAP.EXT add the line:

audIo/x-pn-realaudio ram ra

5. Then make up a command file RAGO.CMD and put in i:\raPlayer\rago.cmd:

/* Launch Real Audio Player for WebExplorer from OS/2 */
/* This was tested on the 0609 WE Beta */
/* Available from URL www.teamos2.org/software/ */
/* Example for RA Player in the I:\raPlayer\ directory */
/* Adjust accordingly */
ADDRESS CMD
'@ECHO OFF'
parse arg infile
'COPY' infile 'i:\raPlayer\FOOFOO.RAM'
'start "RA Player" /WIN i:\raPlayer\RAPLAYER.EXE i:\raPlayer\FOOFOO.RAM'
ECHO Starting the RA Player
exit 0

6. Restart Web Explorer so it will pick up the changes

7. Go to URL www.realaudio.com and have some fun

8. Warning: this is a lot easier than it looks. The only known problems are a brief flash of an OS/2 window, and an unfortunate Windows GPF on exit of the Player.

Product: RealAudio Player 3.0, RealAudio Player Plus

Question: Why do I hear clipped, garbled, jumbled sound from the welcome file after I install the RealPlayer 3.0 on my 486/33 DX?

Solution:
After you install the 3.0 Player or Player Plus the welcome clip that comes up automatically and plays is encoded as an ISDN stereo file. This file requires a Pentium CPU to play clearly, so the behavior you are reporting is expected. You can play 14.4 RA files locally and across the Internet.

Note the hardware difference. A 486/33-DX for playing 14.4 encoded clips and the faster CPU, a 486/DX 66, is required to play 28.8 RA files. A Pentium processor is required to play stereo ISDN RA or RAM files clearly.

For playing 14.4 RA files on RealAudio 3.0, the minimum system configuration is a 486/33DX, 14.4Kbps modem, 4MB RAM, 2MB of free hard disk space, a 16-bit sound card, an Internet connection using a SLIPP or PPP connection to an ISP, Ethernet, or LAN connection, and a TCP/IP Protocol stack (Winsock or equivalent).

To play 28.8 RA files, the minimum system configuration is a 486/66 DX, 28.8Kbps modem, 16550 UART, 8MB RAM, 2MB of free hard disk space, a 16-bit sound card, an Internet connection using SLIP or PPP to an ISP, Ethernet, or LAN connection, and a TCP/IP Protocol stack (Winsock or equivalent).

To play ISDN files, the minimum system configuration is a Pentium processor, ISDN modem, 16550 UART, 8MB RAM, 2MB of free hard disk space, a 16-bit sound card, an Internet connection using SLIPP or PPP to an ISP, Ethernet, or LAN connection, and a TCP/IP Protocol stack (Winsock or equivalent).

To play Dual ISDN files, the minimum system configuration is a Pentium, Dual Channel ISDN modem, 16550 UART, 8MB RAM, 2MB of free hard disk space, a 16-bit sound card, an Internet connection using SLIPP or PPP to an ISP, Ethernet, or LAN connection, and a TCP/IP Protocol stack (Winsock or equivalent).

Product: RA Encoder 2.0

Question: What are the system requirements for the 2.0 RealAudio Encoder?

Solution:
System and Software Requirements for RealAudio Encoder 2.0.

The RealAudio Encoder is designed to work on the Windows 95 and Windows NT environments. The following table explains which hardware is required for specific encoder uses. Note that different hardware is required for encoding from a file and encoding a live audio stream.

REQUIREMENT FILE ENCODING LIVE ENCODING
CPU: 486/66 DX Pentium 75 MHz
RAM 8 MB required 16 MB recommended
Hard Disk Space (software) 1 MB 1 MB
Hard Disk Space (files) 1K per second 1.8K per second
for 14.4 files for 28.8 files
Sound Card 16-bit sound card capable of recording an 8 kHz signal

Note: The Encoder does not support stereo files, or compressed variants of the formats .wav, .au, .pcm. If you encounter problems encoding a file, please verify that it is not in a compressed format or stereophonic. If it is, use a sound editing utility to convert it to a supported format.

The 2.0 version of the RealAudio Encoder can be downloaded from the following URL:

http://www.realaudio.com/products/encoder2.0.html#download

Note: The RealAudio Encoder 2.0 will not run on Win32s for Windows 3.1.x.

Question: Error 41: Requested RealAudio Decoder cannot be found or cannot be used on this machine.

Solution:
Using a 486 SX Windows Computer, or an LC040 Apple Macintosh, you may encounter the following error message when trying to play RealAudio:

· "Error 41: Requested RealAudio Decoder cannot be found or cannot be used on this machine"
· "RA Player caused GPF in Module WIN87EM.DLL"
· "EMM386 has detected error #6"

These errors are generated when you try to play a RealAudio file on a system that is not equipped with a Floating Point Unit (FPU). The real time algorithm used to decode the files requires an FPU(math-coprocessor) because the decoding is math intensive. This error should only occur when trying to play a RealAudio file on a computer lacking an FPU.

The only solution to this problem is to use the RealAudio Player on a system equipped with an FPU. For Windows users, this means a 486DX or Pentium processor. If you use the MacOS, this means a 68040 (not 68LC040) or a PowerPC processor.

Product: RealPlayer 4.0, RealPlayer Plus 4.0

Question: When using the RealPlayer I receive errors indicating poor CPU performance, the Player slows to 0 frames per second or indicates that the system performance is slow.

Solution:
f you receive errors indicating "poor CPU performance", "system performance is slow or the Player slows to 0 frames per second, please verify that your computer meets or exceeds the minimum system requirements.

The minimum system requirements for the RealPlayer 4.0 for Windows 95 or NT 3.51 or better are as follows:

· Windows 95
· Intel 75 MHz Pentium processor
· 16 MB RAM
· 256 color video card
· 14.4 Kbps Modem

The minimum requirements for the Macintosh are:
· Power PC
· 16 MB Ram
· 14.4 Kbps Modem
· System 7.1
· Open Transport 1.1

Note: MacTCP 2.04 or 2.06 will work, but Open Transport is preferable.

These are minimums, and while the RealPlayer 4.0 will run, you will get much better results with higher performance hardware. For instance, the following Windows configuration will give a better playback experience:

· Windows 95
· 120 MHz Intel Pentium processor
· 32 MB RAM
· 16-bit color video card
· 28.8 Kbaud or better modem connection

On the Macintosh, the following system will give better performance than the minimum stated above:
· Power PC
· 32 MB Ram
· 28.8 Kbps Modem (or better)
· System 7.5.5 or 7.6
· Open Transport 1.1.1 or 1.1.2

On the PowerMac, increasing the number of colors the video driver is set to handle in the monitor control panel will greatly improve the ability to handle RealVideo files. This is due to the increased numbers of calculations the display driver has to manipulate to reduce millions of colors to thousands, or 256 in order to display video at these reduced color settings. Far more CPU cycles are required to reduce millions of colors to 256 for example, than to reduce millions to thousands, or thousands to 256.

The RealPlayer's performance will improve with faster processors, more RAM available, and a faster connection.

For Audio Only a 486/66 DX is the minimum Windows based systems. The RealPlayer 4.0 requires a PowerMac as the minimum to run audio or video.

Product: RealAudio Player 2.0

Question: The connection I am using is going at 28.8 Kbps or greater, why do I receive audio at 14.4 only?

Solution:
Many users have connections that have throughput at 28.8 Kbps or greater, but the RealAudio Player 2.0 never indicates anything greater than the 28.8 rate in the status box. The reason for this is that the status box is displaying the algorithms used to encode RA files, not the actual transfer rate.

The RealAudio Encoder 2.0, which is used to make RealAudio clips, supports two encoding algorithms only, 14.4 Kbps and 28.8 Kbps. Regardless of the type of connection, such as 14.4, 28.8, ISDN, T1 or T3 line, the RealAudio Player will only display a 14.4 Kbps network stream, a 28.8 Kbps network stream, or live play through.

Simply put, the RealAudio Player is indicating what type of content it is receiving.

Question: If my system connects at 14.4Kbaud, can it play 28.8 RA files?

Solution:
A RealAudio 28.8 file can be played through a 14.4Kbaud connection successfully, though the sound will be quite poor. This is accomplished by telling the RealAudio Player that the connection is a 28.8Kbaud connection.

To do this, click on the "View" menu, then select "Preferences". In the Preferences dialog box, click on the "Network" tab. Within this tab, set the "Bandwidth" field to "14.4 Modem". Then click on the "OK" button.

While this trick will allow you to play 28.8 RA files, PN does not recommend it because the audio quality will be far less than optimal. Please consider upgrading your modem to a faster model.

Question: How do I determine how fast my Internet connection is?

Solution:
The speed of your Internet connection is determined by the bits per second that data is transferred. This may vary from 56 Kbps (kilobits per second) to 2.488 Gbps (gigabits per second).

The following information outlines the method of connection and the rate per second for each method:

Method = Rate Per Second
Frame Relay = 56Kbps
ISDN BRI = 64 Kbps
ISDN PRI = 23 * 64 Kbps (fractional T-1)
Dual Channel ISDN = 128 Kbps
E-1=European T1. = 2.048 Mbps
E-3=European T3 = Approximately 34 Mbps.
T-1= 1.544 Mbps.
T-2 = 6.312 Mbps.
T-3 =44.736 Mbps.
T-4=274.167 Mbps.
FDDI =100 Mbps (fiber)
CDDI =100 Mbps (copper)
OC12 =622 Mbps service.
OC48 =2.488 Gbps service
10BaseT (Ethernet) = 10 Mbps
100BaseT (High Speed Ether) = 100 Mbps
DS-1 = T1: 1.544 Mbps. In Europe, same as E1: 2.108 Mbps.
DS-3 = Same as T3: approx. 44.736 Mbps

This information can be used to determine what algorithm is the most appropriate for your connection speed.

Product: RealAudio Player 3.0

Question: RealAudio Player 3.0 continues to rebuffer, although I don't seem to have any packet loss. What is happening?

Solution:
If you are experiencing rebuffering with RealAudio Player 3.0, and as a result the sound quality is not clear, but you do not appear to be experiencing any packet loss, this may be due to low bit rates, or a slow connection speed. You may also receive errors about poor system performance.

Check the difference between what connection speed your ISP is providing you and what the requirements for file you are playing requires to be played clearly. You can do this in the Player menu items by going to View, Statistics, Details. Under bandwidth, the top option, "Clip" displays what bandwidth in bits per second (bps) the file requires and "Current" displays what bandwidth or connection rate your ISP is supplying you with.

The behavior that you are experiencing is generally caused by "thin" bandwidth, thus the Player can not support the file you are trying to play.

We recommend you contact your ISP or System Administrator regarding improving the quality of the connection in order to provide a consistent connection at a bandwidth capable of supporting the file format you expect to use. This should be based on the speed of the computer's CPU and the bit rate of the connection, such as a 28.8 modem or a direct network connection like a T1.

For example: Using a 486/66 DX computer with a 28.8 modem, the 3.0 RealAudio Player or Player Plus should be able to play "28.8 Mono, full response" through a 16.0 Kbps connection. If your modem displays less then this in the modem software, or it fluctuates below this then the Player will not be able to deliver clear, refined and continuous sound for this file format. Please see the table below for more information:

The following is the actual bit rate required to transmit each RealAudio codec:

RealAudio 2.0 - 14.4 8.0 Kbps
RealAudio 2.0 - 28.8 15.2 Kbps
RealAudio 3.0 - 28.8 Mono, full response 16.0 Kbps
RealAudio 3.0 - 28.8 Mono, medium response 16.0 Kbps
RealAudio 3.0 - 28.8 Mono, narrow response 16.0 Kbps
RealAudio 3.0 - 28.8 Stereo 20.0 Kbps
RealAudio 3.0 - ISDN Mono 40.0 Kbps
RealAudio 3.0 - ISDN Stereo 40.0 Kbps
RealAudio 3.0 - Dual ISDN Mono 80.0 Kbps
RealAudio 3.0 - Dual ISDN Stereo 80.0 Kbps

The 3.0 Player was designed to buffer in an attempt to improve the sound quality of the RA file that is being played. This behavior is more likely to occur if the clip requires a transmission rate close to the actual connection speed.

There is no easy solution from within the Player to resolve buffering problems or loss of sound quality. You can try connecting at a time when traffic on the Internet is lighter, upgrading to a faster modem, or switching to an ISP with less traffic.

You can also try setting your connection bandwidth to a higher setting than your actual bandwidth. In order to do this, please do the following:

1. Under the View menu, Select Preferences.
2. Select the Connection tab.
3. In this dialog, you will see a option for bandwidth. Set this option to a level higher than your actual connection. For example, if you have a 14.4 modem, set it to 28.8.
4. Select "OK".

Question: When playing an RA file with the Player, I get "Error 19: An error occurred while trying to connect to the RealAudio Server"

Solution:
If, when you play an RA file with the Player, you receive the error message, "Error 19: An error occurred while trying to connect to the RealAudio Server", you may have run into a known bug in earlier versions of the RealAudio 3.0 Server. There are other causes for this error, and are described in the document at http://www.realaudio.com/help/errors/error19.html.

If you get this error on some RealAudio Web sites, but not others, this is the likely problem. This error can occur on builds below 180 of the beta RealAudio Server. In this case Progressive Networks would appreciate it if you notified both us and the Web site of the problem so action can be taken quickly. Please take careful note of the URL for ease of finding the outdated Server.

Thank you for using RealAudio 3.0.

Question: When playing an RA/RM file, on MacOS, displays MacOS error type 1 or type 11, or freezes, bombs or crashes

Solution:
When using the RealAudio Player, RealPlayer or Player Plus, and a MacOS system error type 1, or error type 11 displays on the screen, or the Macintosh freezes, bombs, or crashes, this may be due to one of two possible causes. The first cause is an extension conflict between the Player and one or more non-standard Mac extensions. The second indicates an incomplete installation of the Player. In this case, performing a clean installation of the Player should resolve the errors.

Please perform the following troubleshooting steps to find the conflicting extensions.

1. Check all the cable and connections on the system, and verify that the computer's devices and ports are securely connected.

2. Rebuild your desktop file.
Apple recommends that you rebuild the desktop file after you install new software. To rebuild the desktop file, hold down the Command and Option keys while you restart the computer. Keep the keys held down until you see the alert that reads "Are you sure you want to rebuild the desktop file on the disk "nameofhardrive"?" Release the keys and click 'OK'. The process may take several minutes.

3. Restart the Macintosh with extensions all turned off.
In the Control Panels under the Apple menu, select Extension Manager. If you haven't already named extension set currently in use, do so now by selecting "Save Set" from the drop down "Set" menu and assigning a name. Then from the same drop down menu choose "All Off", restart the Mac, and then run the Player installer. At the end of the installation the Player will attempt to launch the browser, and make a connection to online content. Choose "remind me later" when asked to register.

4.Then, from the Control Panel, Extension Manager select "System 7.x.x " , close the panel and restart the Mac. The system will now have just the standard set of Apple's features and extensions turned on, including Internet connectivity.

5. Once you've restarted with minimal extensions, launch the Player.
Verify that the bandwidth in the Connection section of the Preferences dialog box matches your Internet connection speed, such as 28.8 or T1-LAN. The Preferences dialog is accessed from the Player's Edit menu (for RealAudio Player 2.0 and 3.0) or View menu (RealPlayer 4.0).

6. Next, play the sample file that installs with the Player.
For Player 3.0 the file is thankyou.ra located in the RealAudio Player folder; for Player 4.0, the sample file is thankyou.rm located in the RealPlayer folder.

If the Player works under these conditions, then the original errors were caused by an extension conflict. Follow the procedure below "Troubleshooting Extension Conflicts" to determine the conflicting extension.

Troubleshooting Extension Conflicts

To troubleshoot which extension or group of extensions creates the conflict, use the Extension Manager to add back extensions in groups of five. After each addition, restart the Mac and run the Player. Keep adding and testing until the system hangs or a system error type 1 or type 11 error occurs again. Use the process of elimination on the most recently added extensions to find those which cause the conflict. Checkmarks indicate which extensions are on.

This will enable you to discover which extension(s) are creating the extension conflict. Then create a custom set of extensions which do not conflict with the Player. If you need to use the Extension(s) which cause the errors, for other functions, switch from your "normal" set to your "custom" set when using the Player.

If you continue to receive system error type 1 or type 11 after rebuilding the desktop with minimal extensions, follow the procedure outlined below for "Performing a Clean Install".

Performing a Clean Install

To resolve error type 1 or type 11 perform a clean install of the Player software. To do this; trash or delete the current RealAudio or RealPlayer Player and reinstall the version of Player you wish to use. To delete all RealPlayer files from your Macintosh, including the Player preference file:

1 Select Find File" from the Finder's File menu on the main desktop.
2 Within Find File dialog box, under "Find files on local disks whose names contain __" type the word "real" and click Find.
3 Select all the files that appear by pressing the "command (Apple)" and "a" keys.
4 Verify that none of the files selected are personal files with the word "real" in them, and deselect those you wish to keep by holding down the shift key as you click on them
5 If you do not wish to download the Player Installer again, hold down the shift key and deselect the Player Installer by clicking on it in the list of files.
6 Then drag all of the files to the trash.
7 Empty the trash at this point if you wish to.

Before you run the Player installer again, make sure you temporarily disable all your Extensions. You can do this by restarting your Macintosh with the Shift key held down, keeping it held down until you see the message "Starting Mac with Extensions off". Once this is done, run the Player installer again.

Be sure to turn the standard MacOS System extensions on again. This will restore the Mac's network connectivity.

To do this:

1. Under the Apple menu select the Control Panel
2. Choose the Extension Manager
3. and within the Extension Manager from the Sets drop down menu item, select System 7.x.x

Should these steps fail and MacOS error type 1 or 11 errors continue to present difficulties, or the Mac freezes or bombs, please provide this information to Progressive Networks Technical Support Engineers at:

Question: When I try to install RealAudio Player on my Macintosh, I get the error "The data fork of "RA Player Installer(fat).sea" may be damaged"

Solution:
If you try installing the RealAudio Player 2.0 on a Macintosh, and you receive an error message such as, "The data fork of "RA Player Installer(fat).sea" may be damaged. Use with Caution.", the installation file is probably corrupted, though there may also be a conflict with extensions.

As a first option, we recommend that you try reinstalling the Player from the hard drive with the extensions turned off. This will verify that there either is or is not a conflict with the system's extensions.

If you still receive this or a different error, we recommend that you download the Macintosh version of the Player again because the file is probably corrupted. Before doing this, please check all cables on your system to make sure they are not loose. After downloading the installation file, try installing it again.

Question: When visiting some sites, I receive an error message about "loss correction". How can I correct this?

Solution:
On some sites, you may not be able to play files with the RealAudio or RealPlayer, but instead receive an error message about "Loss correction." This message advises that you go under the View Preference section, click on network tab, check next to loss correction and then reconnect to the URL to which you were trying to listen.

With most versions of RealAudio or the RealPlayer (including Plus versions), you will not have a "Loss correction" option when you follow the steps provided by going to the Preferences menu item and clicking on the Network tab.

Technical Support is researching this issue and we will provide a solution as soon as one is available. The solution will be documented in our online knowledgebase at:

Question: Can I access an SGI's RealAudio Player from an Xterm or MAC-X?

Solution:
While it is possible to access the RealAudio Player via an xterm or a Mac X server, the audio will come out of the SGI computer.

With X, you can display an application on any computer that has an X server running. Currently, there is no portable way to "throw" audio from one computer to another. This problem will remain until there is an audio server available which is universally accepted among all UNIX vendors.

Question: RealAudio for Windows will not load and errors occur

Solution:
RA users running Windows 95 or Windows NT can get various problems and errors when the improper Winsock is used in conjunction with the Player. These include:

· The RealAudio Player will not load
· No sound comes out of the speakers when playing an RA file
· Speaker head icon turns around but nothing happens
· After spawning an external viewer, the message appears in the status bar, "an error occurred when trying to connect to server", or "can't connect to server".
· When the Player starts an error message is displayed or general protection fault occurs.
· There is no document by that name available at the requested location.
· Browser is unable to locate the server :
· The server does not have a DNS entry
· Error 19: "An error occurred while trying to connect to the RealAudio Server."

The 32 bit version of RealAudio 2.0 for Windows 95 and Windows NT requires a 32-bit Winsock. If the browser your system is using is a 16 bit Winsock, the 32 bit RealAudio Player will not work.

There are two options to resolve this problem. The ideal option is to get a 32-bit browser. The other is to install the Windows 3.1x (16-bit) version of the Player in place of the 32-bit version.

The 16-bit version is listed on our Web site for Windows 3.1x It is available at the following URL:

http://www.realaudio.com/products/Player2.0.html

Choose Windows 3.1x as your operating system, and download RA16_201.EXE

Uninstall the current RA Player installation before installing RA16_201.EXE. Having more than one version of the Player installed on a system may result in operation conflicts or failure to run.

You can install the 16-bit version of the RealAudio Player for Win 3.1x using one of these methods:

Windows 3.1x/NT
From Program Manager, select File, then the Run menu item, and then the Browse button.
Find the directory where the web browser saved the file
Select RA16_201.EXE
Choose Okay to execute the file
or
From File Manager, find the directory where the web browser saved the file
Double Click on RA16_201.EXE

Windows '95
From the Start Menu select Run: Browse
Find the directory where the web browser saved RA16_201.exe
Choose Okay to execute the file

If, after installation, you receive the "Helper application not found" message, you need to configure Netscape manually to use the RealAudio Player. This is done by following these steps:

1. Start Netscape Navigator, click on the Options Menu, and select General Preferences.
2. On the Preferences dialog, select the "Helpers" tab.
3. Click the "Create New Type" button. When the dialog box comes up, enter "audio" in the Mime Type field and "x-pn-realaudio" in the Mime subtype field. Click on OK.
4. Under "file extensions" in the Helpers tab, enter ra, ram
5. Select the "Launch Application" radio button, and find the directory in which the RealAudio Player was installed (default is c:\raPlayer). Select RAPLAYER.EXE as the application to launch.

Question: I am receiving Error: WSAENOTSOCK (-1) by RAPLAYER when attempting to use the RealAudio Player/Player Plus 3.0.

Solution:
The RealAudio Player 3.0 and Player Plus 3.0 versions running on Windows 3.1.x may experience the following error: Error: WSAENOTSOCK (-1) by RAPLAYER, when using older versions of Trumpet Winsock prior to 2.1f. More than one winsock.dll can cause additional errors because the system locates older winsocks and uses them instead of the current one which you may think is being used. These errors include:

- "Error 55: Error locating Winsock Services"
· "can't find winsock.dll"
· "Call to Undefined Dynalink"
· "Can't Find TCPMAN.EXE"
· "Error 22: Requested Server is Invalid"
· Trying to connect to another service when already connected
· The RealAudio Player will not load

We recommend you go to Trumpet's site at www.trumpet.com and download and install the most current version of the Win3.1.x compatible winsock. After you have installed the Trumpet winsock in your Windows/System directory, then search for and either remove or rename any other winsocks. If you need different winsocks to connect to separate ISPs, rename them. If you have need for only one winsock, remove all those winsock files not found in the Windows/System subdirectory.

In order to do a search in Window 3.1.x, do the following:

1. From the File Manager, click "File".
2. Click "Search", type "winsock.dll"
3. Start From C:\, Search All Subdirectories.
4. If any matching files are found, they'll be listed.

Any file that is not in your Windows/System subdirectory directory, you should rename it. To rename a file, click on the file name, then choose File, then click Rename. Type in "winsock.old" and hit Enter. Do this for all such files.

5. Repeat the above steps using "wsock32.dll" and "wsock.DLL.

You may need to switch these file names when you need to use software that requires a different winsock other than the current one.

If you have no need for multiple winsocks, then click on the Start menu, and then the Find menu item and look for winsock.dll. Any file you find somewhere other than in your Windows/System subdirectory directory, delete, careful not to delete your new installation of Trumpet's winsock.

Question: Get the error "unable to locate winsock" when using RealAudio Player for Windows '95/NT on ISP MindSpring

Solution:
When using RealAudio Player 2.0 or above for Windows '95/NT over the Internet Service Provider (ISP) MindSpring, the following may occur:

· "error locating winsock services"
· "unable to connect to server"
· General Protection Fault (GPF)
· RealAudio file does not play

The Windows '95/NT (32-bit) version of RealAudio is incompatible with the current NTSI winsock that the MindSpring dialer uses. There are two solutions to this problem. One is to use the Windows 3.1x (16-bit) version of the RealAudio Player instead of the Windows '95/NT version. The other is to set up Dial Up Networking (DUN).

To install the Windows 3.1 (16-bit) version of the RealAudio Player 2.0, first run the uninstall program for the Windows '95/NT (32-bit) version of the Player, then download the RealAudio Player for Windows 3.1, http://www.realaudio.com/products/Player/index.html, and finally, install it.

To set up DUN, please see MindSpring's documentation at the following URL:

http://help.mindspring.com/ng/mshelpfaq.html#2.11

This is titled, "How to setup Win95 Dialup Networking (DUN)". DUN is used in place of MindSpring's access panel.

When connecting to the Internet through MindSpring -- Netscape, MS Internet Explorer, Eudora, etc. can be accessed through DUN. MindSpring provides extensive technical support and help pages though their site at:

http://www.mindspring.com

In summary, MindSpring's current winsock is incompatible with the RealAudio Player for Windows '95/NT. To fix this, either switch to the Windows 3.1 Player, or install DUN.

Question: When playing a RA, RM, or RAM remote file on Win 95 or WinNT on RealAudio Player 3.0 or RealAudio Player Plus 3.0, I receive "Error 19: An error occurred while trying to connect to the RealAudio Server".

Solution:
If you receive "Error 19: An error occurred while trying to connect to the RealAudio Server" when playing an RA file via the RealAudio 3.0 Win '95 Player on a system using a 16-bit dialer or browser or winsock, the problem lies with a conflict between the 32-bit Player and the 16-bit winsock.

Other possible causes for this error are documented at:

http://www.real.com/help/errors/error19.html

If error 19 occurs every time you try to listen to a RA or RAM file on any Web site, but you can play the welcome.ra file from your RealAudio folder, your winsock needs to be updated.

To resolve this error, upgrade your winsock and browser to a 32-bit version, or install the 16-bit version of the RealAudio Player. The ideal solution is to download and install the 32-bit browser and winsock from your ISP (Internet Service Provider's) web site. If you experience difficulties, contact your ISP for information about upgrading to a 32-bit version of winsock and browser.

Question: RealAudio 2.0 for Windows runs, but no sound comes out of the speakers

Solution:

· The RealAudio Player will not load
· No sound comes out of the speakers when playing an RA file
· Speaker head icon turns around but nothing happens
· After spawning an external viewer, the message appears in the status bar, "an error occurred when trying to connect to server", or "can't connect to server".

Product: RealServer 4.0 beta

Question: When attempting to play a .RA or .RM file I placed on my web site, it downloads rather than streams.

Solution:
In order to provide RealAudio or RealVideo content on a web site that will stream rather than download, one of two methods can be used.

The first method for streaming RealAudio or RealVideo content is to use a RealServer. The EasyStart 60 Stream RealServer 4.0 is available for free download from our Web site located at:

http://www.real.com/products/server/easystart/index.html

This version of the RealServer 4.0 allow 60 simultaneous connections to the server and is licensed for live broadcasting.

If your Internet Service Provider (ISP) will not allow the use of the RealServer 4.0, you can still provide RealAudio or RealVideo content on your Web site using HTTP streaming, though the total number of simultaneous streams allowed by this method is roughly 3. Because of this, we do not recommend this method if there will be many people visiting your site all at once.

HTTP enables content providers to stream RealAudio/RealVideo content from a World Wide Web server. While this method is not as robust, it provides a reasonable method for providing content.

Before you can stream clips through HTTP, you must define the following MIME types for your World Wide Web server:

audio/x-pn-realaudio (files with a .ra or .ram file extension)
audio/x-pn-realaudio-plugin (files with a .rpm file extension)

Some World Wide Web servers are pre-configured with these MIME types. For more information about how to configure MIME types for your web server, please see your server manual.

Note: If you are running a web page off an ISP server, send mail to the ISP administrator asking them to setup the RealAudio mime type.

To stream content using HTTP:

1. Copy your encoded files (files with the .ra or .rm extension) to your World Wide Web server.

2.Use a text editor (such as Notepad) to create a metafile containing a RealAudio/RealVideo URL. For example, the contents of your file should be in the following form:

http://hostname/path

where hostname is the name of your World Wide Web server.

For example: www.realaudio.com

Note: Refer to Creating Metafiles. This file works similarly, except it uses http as the protocol instead of pnm.

3.Save your metafile in as text using a .ram filename extension.

4.In your HTML document, reference the metafile in a hyperlink.

For example:

A HREF="filename.ram"
A HREF="http://hostname/file.ram"

You can use relative or complete paths. If you use complete paths, you must include both the hostname and the complete path.

For example:

A HREF="http://www.ra.com/home/welcome.ram"

5.When a user clicks on the link, the audio or video file(s) begin to download. The RealAudio Player or RealPlayer begins playing after a few seconds; it does not need to wait for the entire file to be downloaded.

The HTTP streaming feature is only supported in the 3.0 or newer versions of the Player. If you have a prior version, the most current upgrade is available for download at the following URL:

http://www.real.com/products/Player/Playerdl.html

Please be sure to uninstall your current version of the Player prior to installing the upgrade.
