hmm, great!
i had no time yet to test with wide range of files, but i never had problems
with 24fps movies without this patch. probably because 24<25 so teh buffer
was kept empty all time so buffering delay didn't affect the playback

no, it's another problem
it requires changes in the encoder

and what is, if you change the audio preload in ao_mpegpes.c by +-0.2 now,
with the patch applied?

please also try Michael's libavcodec patch (mplaherhq.hu/~michael/), i have it
applied for some time, probably it fixes this issue too.
