Cannot rip - Bad Disc?



I’ve been trying to rip a disk, Zeta Gundam vol. 9, to my PC. I’ve tried DvdFab (, AnyDVD, DVD Shrink, and DVD Decrypter. DVDFab gets stuck analysing and the latter 3 can’t get passed 60%. DVD Shrink reports also reports Cyclic Redundancy Check. Other discs of the series have burned without any trouble.

I’ve come to the conclusion that it’s a bad disc from the manufacturer, unless someone here has any ideas.
