I will be a little long to explain.
I own a Vitec DCM so i can make analogic acquisition.
I make my acquisition on MPEG-2 , dvd quality.
I obtain 2 files , the .m2v and the .ac3.
I mux them with DVD maker to abtain several .vob files.
Until then all work perfectly.
But when i encode an analog movie (1h30-2h00) , i often leave the computer alone
When i return the movie is encoded but far more than his length.
I got 2h30 for a movie of 1h40 for example.

How can i truncate or delete the vob ?
i need to see the movie to do that.
