Scan and Fix a DVD that has some errors

[ppeterr]

Hi there all,
As I usually do,I backup my purchased dvd's on my hdd so if a damage is being taken into them, I will still be able to preview them. Unfortunately a disc I have recently backed up seems to have some problem,and I guess the mistake is from the ripping program I used(DVD Decrypter). Unfortunately I don't have that disc anymore so I can't do another fresh backup using a different dvd ripping program. What I want to do is to fix this DVD's errors it seems to be having,and re-encode it using DVD Rebuilder, of course, so that I can burn it on a single layer blank dvd(I'm out of DVD+R DL and I'm left with the DVD5's) and watch it. When I choose the dvd as my source on DVD Rebuilder,some weird problem appears. In "Audio" inside "Input Settings" bar,there are 8 channels whereas in the dvd, two are the actual audio channels Japanese and English. The other 6 audio tracks are marked as unreferenced . Same thing happens with the subtitle tracks,while two streams of subtitles are actually on the disc another 30 subpictures appear again marked as unreferenced. So,is there a program that can scan and fix this error so I can re-encode and burn this dvd up? A freeware program, if possible, that can do the job? I would also like to request some full instructions on how to fix this thing up
Thanks in advance

FixVTS. If that wont work buy the movie again and rerip with dvdfab hd decrypter.

This kind of thing happens all the time with foreign language DVDs where they have a bunch of unreferenced languages and subtitles. I have always suspected that some production companies use some sort of default templates in their authoring tools that have placeholders for more languages and subtitles than they really need.

PgcEdit has a method of dealing with this, but I've only used it when making ISO images. Honestly, I'm not sure that this is really and truly a "problem" and you may be worrying about something you can ignore. DVDRebuilder lets you deselect languages and subtitles. Is this really stopping DVDRebuilder from working or are you worrying that you have a problem when as I already said you really do not?

See if it will open in DVD Shrink. If it does, choose only what you need and re-save it uncompressed.

Problem fixed with PgcEdit. I just opened it up and it said about that there were some errors,I answered yes to all and now problem solved .By the way @jman98 DVD Rebuilder does not remove unreferenced material. I found a topic on forum.doom9.org that mentioned using PgcEdit and Clone DVD to clear things up,but I guess I didn't have to use it. Thanks everyone for the help and the fast replies
