a few months ago i burnt a dvd with every season of south park on it, and today i felt like watching it, so i tried copying some off the files onto the hard drive because the dvd rom sorta loud. I get the annyoing cyclic redundancy check. This has happened with alot of cds ive made. I tried installing halo and i got that errors too. So i was wondering, how can i make sure i dont get this error in the future.
