I am always wondering what to do and what not to do so I follow some of these tips.

Hello. I'm a little hazy on what the problem is--maybe someone else has some experience with your particular one. If you can, try CloneDVD or even DVDFab. Decryptor is always good on damaged discs, too. AnyDVD, regardless of the situation, always helps :)Latest AnyDVD to rip > VOBB to blank the unwanted on a DVD > Shrink to compress > ImgBurn to burn = Never starting a thread asking how to backup a movie
