Multiple errors trying to rip damaged DVD

[chunkified]

I have a DVD of an episode of myself in a pilot television program that never aired that was given to me by the producers of the show for my personal use after the editing was finished. Whether by some scratch on the surface or just normal degeneration of the DVD, some parts of the disc won't read properly and I can't load it into a DVD player for some reason. I used DVD Decryptor to rip it and after leaving it running for some days it completed the task and I have my VOB files. But when I try to load them into DVD Shrink so I can re-burn them anew I get "Invalid access to memory location" and "programming error - exception occurred". Sometimes it gets through the whole process only to crash at the end. Sometimes it fails part way through, and it fails in different parts. Sometimes it just locks up. I can see where bad parts are because there's a bright green bar in the preview mode on some shots. Sometimes the preview mode works, sometimes it doesn't. It's just very inconsistent and doesn't make sense, especially since no matter how many times I try, it always fails.

I'm not sure if this DVD was encrypted but I don't think it would have been.

Any ideas?

Since Shrink opens the disc I'm not sure the exception occured is really a problem of the disc being degenerated. What do you need Shrink for, does the material not fit on a blank disc as it is? Also instead of DVD Decryptor you should try Isobuster or some such tool (if disc IS encrypted also with AnyDVD in the background) to try to rip a better version of the disc.

Tools that are designed to read scratched discs might yield better results than old DVDD, also ripping with different drives might help.

DVD Decrypter has an option to ignore errors and set retries to read to 0. This way I have managed to rip most of my broken DVDs.

Let me know if you need more help.

As a last resort, you might try using plastic polish purchased from an auto parts store.
I can usually recover unreadable disks this way.
