I have several .mkv files (x264) movies and they play fine except for one which the audio will start to go out of sync by about 3 or 4 seconds. I have Haali and FFdshow tryouts installed. Is there anything else I can use to troubleshoot the issue. Is there a program I can use to see what audio file is being used in the .mkv file that wont play? This file plays fine on a friends computer with no audio sync issues and hes running comparable hardware to mine. I have been reading about possible needing to use avi synth? or the video was muxed in 29. fps and needs to be 23? Vorbis audio causes syncing issues? I just dont know where to begin to troubleshoot this.

TIA
