Typically when I encounter issues with a DVD, it's caused by dirt. I clean the surface then try again. But, once dirt has been eliminated as a problem, then most likely it's a DVD player problem, especially if the problem occurs on DVDs that have played fine before. Yes, there are DVDs around that do have problems, but they aren't too common.
I have a large screen, rear projection type, TV. It came with a surround sound home theatre unit and a built in DVD player.
Recently, I have noticed DVD's freezing for a few second, playing normally, and then freezing again. This has happened on two diffrent discs of a boxed DVD set that I have, and just recently on a movie I rented.
Could this be common on DVDs, or should I be expecting problems with my player?
