 I did not even know this was a thing. DVD rot. You see around the edge of the DVD there where it's brown. Well that is basically the DVD kind of rotting away. So you fellow DVD and Blu-ray hunters, be careful and open up the discs to make sure that they're not rotting away before you buy one. I didn't even know this was a thing, but found out the hard way, put in the disc, and it didn't play. So beware of DVD disc rot.
