When trying to back up this disc it gets to 43% and then screams to a halt. After many, many minutes (several hours) it has reached about 70% and then slows right down again. Eventually it simply gives up altogether with a message saying it can't copy the disk (DVD NeXTCopy). I have also tried backing up with AOA DVD Copy but it exhibits the same exhibit symptoms. AOA does, however, give me a "Sector Too Large Contact Apollo Software" error message before dying. Any suggestions? I will try turning off the Jump to Main Movie option, and if that doesn't work, I'll post the Information window when I get home. Thanks.
