You aren’t able to watch a movie over again because the screen says, “Unable To Read Disc.” Why? Because of the scratches. If discs aren’t made to be scratched, then why are they able to be? They should have a protective layer so they don’t get scratched. That’ll save someone an extra twenty bucks from buying the same movie over again. Even worse, people who don’t know how to put a DVD back in its case when they’re done watching it.
