"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 ...

Yes but they’re brand new discs.

Hey all, I'm getting this commentary when I'm trying to back up my NCIS Hawaii Season 1 DVD... any advice?
