VOB to MPG results in decreased time?

[kpic]

I am having a lot of difficulty with a VOB file from an "extras" scene from DVD the scene is 26m 18s

Here is what I usually do: DVD Decrypter (Audio Demux) and rip it and the video (not demuxed) , re-encode in Procoder and then to my authoring program (Encore) - never had an issue this way until now.

Here is what is happening; for some reason the resulting mpg is at 25m 56s (the ac3 is the correct 26.18) but it is all there nothing is missing from the video and it is clear it is just "short"

I have tried a lot of different methods (Mpeg-VCR which resulted in the same length) but I always end up with a short mpg.

I also tried to use DVD Decrypter in the "demux" setting for the video and the result is the same a shortened time video.

BTW I also tried DVD Fab which gave me two VOBs I then merged using VOB Merge and then ran through Procoder with the same result.

I know the original VOB that I rip is causing the problem, and would assume it is corrupt in some way but not sure what it is and how to fix.

I see three ways to fix this; fix the original VOB, shorten the AC3 length or increase the video file to match (not sure if those are possible)?

Just to update;

I tried a program called "FixVTS" (the VOB views fine) and ran the resulted "Fixed" vob through Procoder and I get just the first 2 minutes of the video encoded, even though upon input it gives a time of 27m.

I took the "Demuxed" video from DVD Decrypter and opened it in TMPGENC 4 and it claims it is 1 second long with "1" frame.
