I had thought about disc rot... but after only what, 5 years? I suppose that is the answer though, the disc is pristine as far as I can tell. No matter, the bluray is cheap.
The drive is hooked up to the slim 360. From my entertainment center, I can't hear the 360 or PS3 slim spinning discs when playing movies, but I definitely hear the HD DVD drive. Maybe it's time to either get a new HD drive or just purge the movies and get the important ones on bluray, they should all be cheap by now. It's not like I have a huge collection, it's mostly just stuff I could get cheap back when it was all clearanced.
