Great job on the WMV3 decoding!  The lack of an open source codec for  
the MSN voice/video protocol has been a serious impediment to getting  
MSN v/v working on the Mac.  (My understanding was that Linux  
previously only worked because mplayer used the windows media player  
DLL in compatibility mode.)
