DVD Fixing software

Alright to make a long story short I have a copy of a dvd that the original was stolen (lost one of my cd cases and radio out of my car ): So I decided to back up the copy I had at home. For some reason there is a problem with the vob 7 and its extensions. I’m not new to backing up my movies, but I’ve never ran into this problem. What programs out there can I try to use to fix it. Ive tryed dvdfab,nero, decrypter and tryed reencoding it and disc to disc. It won’t let me even put it on my hard drive. It also plays fine in my dvd players ( tried all 3 that I have).

it won’t work…you can’t rebuild the damaged file…have to have the original disc
