I'm using DVDFab 188.8.131.52 to rip a new box set I bought. It's 8 seasons with 5 discs per season leaving me about 40 discs to rip. The first season went fine, no problems at all. The second season I had issues with discs 2 and 3 stopping in the middle due to a read error. The third season did exactly the same thing on disc 4. After that, the rest of the entire box set ripped completely without any issues and no errors. I thought there might be an issue with my DVD drive but I only had that problem on just a few discs. I also tried using a portable copy of DVD Decryptor on those bad discs and it seems that, after many retries, it was able to rip it successfully. My question is, is it normal for some DVDS to not rip properly because the way they are made? Otherwise it would seem the issue is either with my drive or software and I can't see what those issues would be. Thanks!
