.mkv exporting problems

[VHS_UK]

I don't get what you want ot show me with the two screen shots:
1. they show different frames
2. they show different times
3. there is no indication of audio on any of the two screen shots.
-> not sure what you want to tell me with them.

Cu Selur

It's hard to describe, like if you play them simultaneously you can notice the audio would play in a slightly different part of the video on the edited .mkv.
