ofps 24000/1001 -vf crop=720:352:0:66,filmdint=fast=0,softskip -

Underworld_Evolution.mkv

This so far is by far the best. Got a complete output file though a
bit larger than I normally get when converting DVD to AVI. This
one's about 1.7 GB which isn't a deal breaker.

Sound is almost synced in this one - only off by a fraction of a
second, just enough to be annoying.

What setting should I tinker with to get the sound matched up
perfectly?

Tried first with "-mc 0 -noskip" but output file was truncated and
corrupt :(
