Has anyone here had issues with the last movie or any of the movie in the Planet of the Apes box set being defective. My neighbor had purchased the box set from Costco and was not able to play the last disc. Now usually it ends up being a firmware update but if all the other discs in the set play you would think that wouldn't be the issue. So after bringing the disc over and I tried it in my Denon 1611 and it said unknown disc and didn't even try to play. Then I took it to my pc which has a lite on rom and it said no disc. So some how I seriously doubt with a Sony BDP-S300 which I am sure has the latest update that belongs to my neighbor, my Denon DBP-1611UD and Lite On Bluray rom all saying unknown or no disc I have to wonder how many have had issues with this set?
