      Problem: RealAudio/Realvideo on Athena 

 A common problem encountered on Athena when using RealPlayer to view content is that your Netscape
 preferences may be set to run an older version of RealPlayer. If so, you may get an error message that is
 similar to:

     sh: raplayer: not found

 Another problem encountered when using RealPlayer on Athena is that the player is displayed but never
 contacts the video server, and the video screen stays blank. If this happens, the current version of RealPlayer
 is correct, but the play specification is incorrect.

 Here is how to check for and correct either problem:

      Start Netscape. 
      Select Preferences under the Edit menu. 
      Click on the arrow next to an additional list should drop down. 
      From this list, select Applications. 
      Scroll down in the Applications menu until the description field reads "RealAudio." 

 The "Handled by" field should read:

    realplay "%s"

 If it does not, but instead reads either raplayer "%s" or rvplayer "%s" or realplay "%u", you will need to
 change it. Do this by selecting RealAudio and clicking Edit. Change the application command to:

    realplay "%s"

 and click OK. Click OK again to close the preferences box. Quit Netscape and run PIVoT again. If this does
 not work, or if you have other questions or difficulties, please contact us at pivot-support@mit.edu.





On PCs/Macs

 Viewing RealNetworks content on either a Windows machine or a Macintosh requires the RealNetworks RealPlayer G2
 or higher plug-in. If you are working on a PC or Macintosh and do not have this plug-in installed in your web
 browser, please go to the  RealPlayer download site.

 (Athena users: The setup sequence for Athena described below automatically installs the RealPlayer for Unix.)
