well, just for the records... the computer where it was
ported/developed/tested (mine :) is an athlon xp 2000 with matrox G450.

i can enable pulldown detection (it eats more cpu when it doesn't detect
the pulldown - if it does the framerate is decreased), greedy2frame and
even chroma filtering at the same time without using all my cpu.

btw: i plan to add some small hacks to tvtime so it can use less cpu as
a tradeof for quality. if anybody cares, the older deinterlace code (in
XV driver) used some of the same algorithms of tvtime. those work on
images at YUY2 format. however, unlike the new tvtime plugin, it did not
convert the frames from YV12 (libmpeg2 output) to YUY2. so the result
was less accurate but "cheaper".
