Just called 1-800-4my-xbox and told them I have been getting dirty disk messages, game freezes, and lots of noise from my DVD drive. Bought my Xbox last year in December and have no extended warranty. Had read on teamxbox that others had been given free repairs, so gave it a shot. The guy I talked to registered my xbox as it seems I hadn't done that last year, then told me it was still covered under warranty and would be fixed for free. Apparently, MS has realized that many of the origionals had drive problems and has extended the warranty period. Just a heads up to anyone else having the same problems.
