That assertion is indeed incorrect now, but the problem lies even 
deeper. Neither our MPEG2 decoder nor xines software decoder can handle 
4:2:2 streams, so I couldn't find a way to test that probably. Xine is 
just checking for YUY2 support before using VDPAU in any way, so with 
that patch you can at least play 4:2:0 streams.

Thx for the tip with mplayer, it looks like mplayers software 
decoder+VDPAU can actually play those streams, so I now was able to 
hammer out some of the bugs. But sampling from those packet formats is 
still a bit buggy, need to work on that a bit more before I can commit 
those patches.
