Can I edit video_ts.ifo to link missing vobs to DVD?

[Srivas]

Hi!
I hope I express myself correctly, but my problem is that I have some dvds, authorized in DVD A, but they were authorized with a mistake, Set Out Point was set too early, so the dvd will end all of a sudden in the middle of the movie.

My question is: Is there a way to edit video_ts.ifo (if I understand correctly, this file is responsible for the dvd stucture), so that the end point of the whole dvd would actually be at the end? Because after authorizing the dvd, whole dvd material is there, but I want to add up the unreferenced material.

Is there some easy way to do it?

I did some research and came to the program pgcedit, but if that is the way Im suppose to go, can anyone explain how to do it there?
Thanks.

probably easier to re-author the dvds. you can always change the vobs back to mpeg-2 with vob2mpg and import them back into dvd a, if you don't have the original source any longer.
