Installed DVD Shrink last night on two PC's, both running Vista, both brand new PC's. One will backup anything I put in it. The other will not back up anything. It always claims that the DVD's are copyright protected. This after just having backed up fine on the other PC. The only think I can figure is that the DVD burner on the one that doesn't work is causing the problem. Any ideas? I really love how fast this thing will back up my collection so I don't have to be a slave to the PC. It's ingenious.
