Issues when removing the CompactFlash™ during operation
Removing the CompactFlash card while the MCU is in operation has been known to cause a restart.
Windows Media Player
Streaming a conference with Windows Media Player in multiple windows or tabs on the same browser will crash the
browser. This is a known issue with Windows Media Player. If you need to stream more than one conference
simultaneously, use a different player such as QuickTime or Real Player.

simultaneously, use a different player such as QuickTime or Real Player.
In addition, Windows Media Player 11 (WMP11) can display streams incorrectly when used as an embedded player
with browsers other than Internet Explorer. This is a known incompatibility. In some cases, setting the video size of
the main streaming video window (the Video size field in the Streaming page) to Large will correct the problem. To
work around this issue, you can use QuickTime or RealPlayer instead of WMP, or use Internet Explorer instead of
your normal browser.

Streaming to QuickTime 7 causes problems with some browsers
Streaming to an embedded QuickTime player using the QuickTime 7.0 plus later option for the Player format on the
MCU can cause certain browsers to crash or remain in the 'negotiating' state indefinitely. Affected browsers include:
IE6; Firefox 1.5 (Mac and PC); Safari 2.0.3 and earlier, and Camino. IE7 and Safari 2.0.4 do not appear to be
affected by this. Using the QuickTime 6.5 plus later option for the Player format on the MCU will allow streaming to
QuickTime using any browser that supports a QuickTime plug-in.
