I am trying to rip some backup copies of some dvd's. I must include that I have had success in the past with other dvd's from the same box set. The first problem is one of the dvd's gets an error 2/3 of the way through the intial analysis stage in dvd shrink. I have tried rebooting, cleaning the dvd, but it keeps getting stopped in the same spot. Has this happened to any one? The second problem is, I am able to ripp the dvd to my hard drive with very little compression, but the files from chapters 20 to the end are pixelated. (DVD shrink also will not allow me to edit via start end with this disc.) Is this a common problem? Please help.
