I was watching a burned dvd recently and noticed that the audio quality sounded pretty bad. I'm not sure how to describe it. It sort of sounds old and crackly. The weird thing is, I've watched the dvd before, on the same dvd player, and the audio was fine. So, I switched to another dvd (also burned) and it sounded poor as well. My next idea was to try the dvd on the computer to see if maybe I compressed it too much and the quality lowered as a result, but it sounded perfect when played on a computer. Is this a dvd player problem, or a dvd problem, and how do I fix it?
