I recently made a check on one of my home burnt dvd's and found out that the sound on some of them have somehow turned out to be faulty. I still got the original soundfiles left but since the videosources are gone it would be hard to recapture them again.
Since not all of the videofiles on the dvd's are faulty I was wondering if there is any way to replace the faulty audio by "deauthoring" (?) the dvd, if you see what I mean.

I know how to rip vob files and such, but I would like it to come out as editable with menu and all so it's only needed to replace the audio itself.

Is that possible?
Open for any suggestions.
