Either that, or mplayer does not keep sync be default. To find out, play the file with -speed 0.2: It A/V sync is ok (watch the "A-V:" value in the status line), it is a hardware problem, if not, (at least) an mplayer problem. > If not, how can I tune to sync audio with video? If your hardware is not fast enough, try: -lavdopts skiploopfilter=all (whould improve speed without visible difference) -lavdopts skiploopfilter=all:fast (nearly no additional speed difference) -lavdopts skiploopfilter=all:fast:skipframe=nonref (skips every second frame) If it is an mplayer problem, try: -demuxer mkv -nocorrect.pts -demuxer lavf -nocorrect-pts -demuxer mkv -nocorrect-pts -mc 1 -demuxer lavf -nocorrect-pts -mc 1 (It is possible that you have to combine both methods if the file does contain PAFF frames - the reason for a mplayer problem - and your hardware is too slow.)
