this is not problem. it's a missing feature.
i mean: no one optimized the 24bpp version of YUV->RGB converter (it's used
by vo_gl).

yes. it has changed with new audio code.

dunno. it changed a lot, i think it's ok this way. but Nick will
hopefully check.

it's like SDL

it can't position to exact frame position.
reason for mpeg/asf: there is no frame/time indexing, it uses average kbps
value (so +- 10% is ok...)
reason for avi (divx): keyframes are 10-20 sec distance, so it will find
the next keyframe (so + 0-30s).

this should go to FAQ!!!

yes. dependency is a big hack now... (still :))

i know. but can you fix it?

I know :)
Just watch a brithney spears clip at 120khz :)
