Well, scaling and YUV conversion are fully accelerated using Xv, also
there is xvmc, which allows hardware acceleration of parts of MPEG 2.
But the real issue is that there just isn't any hardware for H.264 and
VC-1 acceleration right now, other then the CPU and it's SIMD options.

(For MPEG 2 playback there are also dedicated decoder cards, but those
don't have much of a generic api, though work fine in mplayer thanks to
some diligent coders).
