I just looked at why this wasn't applying. Basically I had stealthily
been adding bob-deinterlacing to xvmc, but while I was preparing for
SIGGRAPH Doug went ahead and added it. So a lot of the conflicts were
just two versions of the same thing. The patch does three other things
which I'll be submitting seperately soon:

 1/ It uses flush, and not just sync to let the video card process
    more things in the background.
 2/ It fixes some locking issues, that should avoid getting stuck with
    unusable XvMC surfaces in many cases.
 3/ It rewrites some of the ffmpeg stuff to be clearer and more
    efficient, and easier to adapt to MPEG4 acceleration.
