I guess this could be a problem in libavcodec, rather than XvMC. I 
presume this code should just send the video stream to the HW MPEG 
decoder. Maybe it is striping off the first audio stream for sound
and sending the Video + Audio to the hardware decoder. This would 
probably break a HW video decoder ....

I wonder if any other HW MPEG decoders are having the same problem ?
