I'm using mac the ripper on two computers, one is a G4 Tower a few years old and the other is a brand new Power Book, both using Tiger. The Tower has been copying fine, my player/burner is a Pioneer DVD-RW DVR-104. The PowerBook has a Matchita DVD-R UJ-835E that came installed in it. When using Mac the Ripper on the Powerbook, it copies like normal, and at the end I get a message saying "Bad Sectors". From here the TS File is useless, no playback and cant burn it using Roxio Popcorn. The Bad Sector Message appears everytime, everydisc I put in there. I deleted Mac The Ripper and tried a fresh download, still did the same thing. Please let me know if you have any comments or suggestions for getting my Powerbook up to par.
