Failed to open disc

The unrecovered read errors are a bad sign. Have you tried gently cleaning the disc?

Yes but they’re brand new discs.

Maybe another DVD opening mode can help: viewtopic.php?f=7&t=28541

"Brand new" means nothing as far as clean disks. Packaging of disks can cause contamination that makes disk hard to read without cleaning.

If I get a title that's freshly-distributed, it's less likely to need cleaning. If it's been around for several months, then I keep the cleaning stuff handy.

Thanks for the advice, I’m new to backing my stuff up, only been doing it for the past few weeks
