user1901: I use mpeg streamclip to fix the timecodes in merged vobs. I would like a command line utility that does this without having to recode if possible.

user4943: Libav has the tool avconv, which allows you to do that with the video filter setpts=PTS-STARTPTS.
I haven't tried this, but the following should do the trick for you:
avconv -i in.vob -vf 'setpts=PTS-STARTPTS' -c:a copy -c:v copy out.vob
