Are you sure it's just fine, though? In NTSC land, at least, whem
mencoder is skipping frames the encoded video "jumps" a little bit
whenever the frame is skipped. You have to look closely at some scene
with constant motion (like panning) to see it.

Do you have access to post a small portion of your DVD image on some
http or ftp server so I can download it and experiment?
