hi,

we need to replace our idct. the present mmx/xmm code (peter
gubanov/mpeg2dec) produces errors, which become quite visibile in
quarterpel mode. our current integer idct also produces qpels errors..
which makes me curious about the sse2/ppc/ia64 stuff.

anyway, i think we should switch to michael niedermayer/ffmpeg's
simple_idct. it is fast and produces much less error.
simple_idct_mmx is written in gas... so will anyone object to me
commiting a nasm'd version?
