Only one of my DVD's was loose and scratched. It plays fine, but you never know what will happen in the future. I paid for a pristine DVD, so that's what I want. I contacted CKSales (I ordered through them), and they promptly responded. They said that they will get a replacement and a return mailer out to me ASAP, but it might take a couple of weeks because they are backlogged.
They also said that this has been happening alot with the HardCore DVD's. :-( I'm just glad only 1 out my 11 had the problem.
