Streaming issues with Windows Media Player from Cisco acquired Codian products

Why am I having issues streaming with Windows Media Player from a Cisco acquired Codian Conferencing Product?

Windows Media Player is only supported on machines running Windows NT, 2000, XP or Vista, and requires the installation of an audio/video codec. An installer for this codec can be downloaded from a link on the streaming page of either a Cisco TelePresence MCU or IP VCR unit, or MSE 8000 MCU or IP VCR blade. (The codec is listed as the Codian Video Decoder in Control Panel > Add/Remove Programs, and can be uninstalled from there.) Installing the codec manually should allow streaming to any browser that supports Windows Media Player for displaying embedded media.

If you are using a browser other than Internet Explorer to view streaming video then you may experience problems using Windows Media Player. Support for Windows Media Player varies from browser to browser, and there are a number of known issues particularly with Mozilla Firefox and Netscape, including the browser crashing when the window is closed, or the video disappearing while the controls remain (this can be temporarily remedied by moving or resizing the browser window). In addition, the aspect ratio can be wrong in small windows when using WMP and Firefox, but that can be corrected by downloading the patch from the following web page: http://port25.technet.com/pages/windows-media-player-firefox-plugin-download.aspx *. These issues are less likely with an MCU or IP VCR running version 2.0(1) or later.

If such problems occur, then ensure you have the latest version of the browser and the most recent version of the Java plug-in* from http://www.java.com/en/download/manual.jsp (there is a known issue with Java conflicting with Windows Media Player 9 in certain browsers). If the problem persists, then consider using a different browser or a different player to view the streaming media.

Note that Windows Media Player is not supported for multicast streaming.
