I don't think it can work with the current ffmpeg. When I tried running 
mplayer with xvmc I got:

Forced video codec: ffmpeg12mc
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Cannot find codec 'mpegvideo_xvmc' in libavcodec...

I looked through the code and don't find mpegvideo_xvmc. Some ffmpeg 
documents say mpegvideo_xvmc had problem. It may have been removed, don't 
know. I've put a couple messages on the ffmpeg list but got no replies.
