You regulars may not believe this, but: My daughter scratched up one of my original DVDs pretty bad. I tried to copy it so that I would have a backup. I had 4 VOBs that ABSOLUTELY would not copy. I tried the toothpaste trick, but it put a lot of swirl marks on the disk and the same files would not copy. As a last resort, I tried some Turtle Wax scratch and swirl remover....... Viola. Everything copied and the drive didn't even slow down when using DVD decrypter. ~5000 kb/sec. Of course, I tried it out on an old AOL freebie that I got in the mail first.
