i can't seem to backup this disc from the show 24 season 4 disc 3. i use clonedvd 22.214.171.124 and i have also tried nero 6, but i get the same problem. it stops processing the disc at 50% every time. i also have tried two copies so it cant be the disc itself. i have attached an edited log file (space limited by forum) from clonedvd. thanks please help.
