I've been trying to backup my DVD. It has 8.1GB of content. I tried doing a disk copy before and it failed at the 400MB mark. Then I used Mac the Ripper and did a full extraction to my MacBook Pro. Then I used Titanium Toast 10.0.6 to try writing another CD. This time it went farther but failed at the 27% mark. I don't know what to do. Do I have a bad batch of Blank dual layer dvds? I bought them at the apple store 3 years ago. They are made by Verbatim 8.5GB blanks. Any one know whats wrong? Below are screen shots of the error it giving me.
