Well, the AltiVec code in ffmpeg doesn't improve any relevant part in
mpeg2/4 decoding. I'm still trying to figure out which boundaries the
code can rely on to get some more altivec code in; currently it breaks
every other day with different video material because the data is
aligned differently. :/ A general approach would be possible but obviously
not very speedy.

That having said, I've found *one* function which will run raster on G3 
functions when unrolled per hand. Doesn't make much of a difference though
in wall time.
