You suggestions have no effect on my files. Problem is not solved. Playing with key -bps even worst than
without. I have found that audio & video streams are resync after overloading of CPU. If key -bps is not used
there is possibility to sync streams again, but with -bps streams never sync.
Exampe: I watch the film 'Species' with russian translation. This film have size of picture 600x400. (4:3 format)
In the places where story is very dynamic my cpu is overloaded and after it sound outdistance from video on
3-5 sec. After pressing left and right arrow keys (sometime 'P' - pause key) streams are sync again. But if I use
-bps it's not possible and streams never sync again until of end of film.
I've understand that would be better to change my PCI S3Virge with AGP video card, but:
Are there possibility to avoid this problem or it's not possible for mplayer, because it uses codecs with closed
