I picked up a Sony NA a few days ago and was anxious to test it out, but was disappointed to find I couldn't get past the menu screen. When I click on the set-up screen, after some loading a window pops up saying the disc tray is open, but it isn't. I'm not sure if it's the disc's problem or if Sony implemented some sort of modchip protection. Has anyone else run into or heard of a similar issue? I've got an Apple Chip (Apple M3, I think) in my system. Any help would be appreciated, thanks.
