How can I fix the playback time of a title when replace the VOB?

[Massa]

I want to change the VOB of a DVD but keep the menus and everything else and do not reencode the VOB.
My problem: I can change the VOB, but since the original was much shorter, the new title will play only up to the duration of the original VOB.
I tried using PGCEDIT but I am not an expert and it seems that it is limited to adding chapters in the middle of the reported duration (the wrong duration) but won't let me change the playback time to include all of the new VOB.
any help?

Wrong tool ... get vobblanker and jobs done

Is there a tutorial?
my impression is that the program wants to cut the VOBs to ge to the IFO theoretical duration, but what I need is the other way around.

Since it sounds as if you're trying to reauthor with a combination of new and old elements, you may be better off simply reauthoring for real (although there are other methods). Try GUIforDVDAuthor; it's free, and quite flexible (certainly more than powerful enough to do what you need done). I'm sure you'll get other suggestions from other folks, so if you don't like this one, just wait a bit.

Vobblanker is pretty easy.

1: Hit "browse" on input, locate ifo of title
2: Hit "browse" and set location for output (different folder, and make sure space is available)
3: In lower window, locate title to replace (duration time will give it away) ... click to highlight it

Now more info displays in lower window

4: Click to highlight the title you want to replace in lower window
5: To the right, hit "replace"
6: Locate first vob of replacement title

Hopefully there are no errors ... none if both use same internal format specifications

7: Hit process and wait till done

Again, if all's well, there will be "success" message

8: Always playback on pc before committing to media ...

And yes, a similar thing can be done using pgcedit

To give more background, I built a very nice menu and intro with Mac's iDVD.
The material I wanted to add where already encoded to MPEG, so, I just muxed it as VOBs.
I authored a fake DVD with very short videos in iDVD, and later replaced the VOBs....it worked, but only with very little duration....
