DVDDecrypter and Stream Processing Problem

[RTailor]

I have a DVD9 i want to put on to DVDR I only want the main movie so i am trying extract the streams only m2v and ac3 so i can re-author them with my own menu.

BUT

The movie is 2hr 10mins long and i used DVDDecrypter to grab the streams into one huge VOB. I then loaded the VOB into MainConcept and the time it gives for the duration of the source is only 20mins!!

How is this possible because the VOB is 5GB!!

Is this a problem with DVDDecrypter or MainConcept?

Shall i use graphedit and extract the m2v from the VOB and try loading that into MainConcept?

Any ideas anyone?

I have worked it out, it must be the way Mainconcept imports the VOB but it wouldn't pick up the full duration of the source, so i used Graphedit to demultiplex the streams into elementary streams and loaded the elementary streams into MainConcept and it picked up the correct video duration.
