I believe that it may be a NVIDIA DVD Decoder problem since I have exactly
the same problem with my dual boot system of which only the Graphics card
driver is different between XP SP2 and Vista RC2 and since my graphics chip
is an Intel and not and NVIDIA I thought at first that it was an Intel Vista
driver problem. I am using DVD Decoder 223 on both systems.
When I play exactly the same MCE TV program file with Media Player first on
XP with Hardware acceleration enabled I get DXVA mode, however, then I play
it again of Vista with hardware acceleration enabled I get YUY2 mode.
