What about -vn -sn?
Does that change anything?
(Just to understand the problem you see.)

If you play the original vob file with ffplay and seek 
(with "up" and "page-up") do you see monotonic timestamps 
in the console output or does something funny happen?

Can you upload the sample that causes the memory problems?
Does it happen with all vob files?
