hmm
IMHO the max benchmarks are meaningless, u should at least count the number 
of frames which are too slowly decoded, instead of finding the slowest one

i saw this juddery playback too, but imho its not cuz a rare keyframe is 
decoded too slow (as appearently u suggest)
what i saw is that if i playback the same movie with the same commandline
its sometimes perfectly smooth and sometimes nearly all frames are juddery, 
and that only happens if double buffering is used so i guess that somehow the 
displayed frame is the wrong one of the 2 in the buffer sometimes ...
