Not true.  You could also use VLC (which I recommend over MPlayer), or 
QuickTime Player (if you're streaming MPEG-1 rather than MPEG-2).

MPlayer's audio/video sync implementation doesn't always work well for RTP 
streams.  That's one reason why I prefer VLC.

Exactly.  This is an OS issue - not an inherent problem with the "LIVE.COM 
Streaming Media" code.
