I've had an Apex Ad-2600 for probably 8-10 months now. All my DVDs work fine except Spider-Man Disc 2 (special features disc). I put it in the tray and it "loads" then I get the "no disc" error. There's no scratches or dust on the bottom, but it does (on the label) smell different than my other discs. BTW, the disc works on my Xbox.
