I tried to backup South Park Season Thirteen that I bought last week.
I have always been able to backup with DVD Decrypter & DVD Shrink--sometimes having to use FixVTS for some DVDs that have dummy sectors.
When I backed up disc 1 & 2, always backup to hard drive, one disc was 38GB and the other disc was 42GB. I would not have believed it, but seeing is believing. I tried RipIt4Me(which includes Fix VTS), but still HUGE results.
I installed a trial version of AnyDVD & CloneDVD, and was able to backup my entire boxset--no errors.
I've noticed when researching the HUGE ripped file results, there's some other DVD's with similar problems--
Princess & the Frog
I might be buying AnyDVD & CloneDVD if this protection system keeps showing up.
