Trouble copying Nip/Tuck Series

I am having trouble copying any of the Nip/Tuck series. I tried using dvd shrink, dvd decryptor, and dvd fab. About a half hour in to the disc, it starts stuttering, would be the best way to describe it. Like if the dvd were smudged. I cleaned the dvd before burning it with a dvd cleaner. For some reason, it keeps happening. Is there some kind of protection on here? Has anyone encountered this also? Usually if I have problems with shrink, I use DVD Decryptor and it works for me. Any help would be appreciated.

I had no problems backing-up both season 1 and season 2 DVDs using DVDdecrypter (ISO to hard drive), Daemon (mount ISO) and CloneDVD2, perhaps you should give it a try…
