I am am backing up some already backed up discs, a.k.a the discs I have are dvd+r's. I have DVD shrink and decription software. The orginial dvds are from China. If you are interested it is like a 25 disc set of all the G1 cartoons plus the movie. The set is on amazon, and yes they are in english. I digress. I have copyed all but 3 discs and they will always get to about 70% analyzing and stop. It moves very slow and takes an hour for it to analyze. If anybody has any ideas I would love to hear them.
