At first from DOCS/BUGS:
#- your soundcard doesn't support 48Khz playback
#  Workaround: buy a better soundcard... 
#             or try to decrease fps by 10% (use -fps 27 for a 30fps movie)
I have SB16 which can play only 44100 but I've watched almost film entire (first 2 hours 45 min) without any 
problems and without a-v resync. Arpi probably fixed this by syncing each frame.
Second:
I would be glad to upload "bad" piece of avi but not entire avi - because avi have size about 700Mb
but "bug" is occured withing last 15min of film. How I can cut out "bad" piece? I tried cut out one avi
(I've cut only first megabyte of file) and mplayer says that this avi have no indexes and seek not possible.

Best regards! Nick (2001-06-03 13:29:45)
