What's strange here though is that this same skipping happens also at the 
start of every chapter, if you specify -chapter xx, so you don't start from 
the ... start! But if you start from the beginning, at the start of the same 
chapter there are no skips. Could it be some problems mencoder has when 
starting to read VOBs? I assume I'm extremely picky, because 2 or 3 frames 
causes a sufficient desync for me to detect it, especially in original 
language, so I would be very keen to correct it.
Thanks again!
