Anyone using Nero to burn dual layer discs. I'm turning loads of discs into coasters here as after every burn my DVD plays for a while then freezes on me. I've run a check on each one and it shows the error "cyclic redundancy check" which I believe is a code for bad media. Thing is the discs are fine before I burn them. I know this is a bit specific but just thought I'd float it to see if anyone has a view.
