I am trying to playback Avatar ECE Disc (Region B), all the discs seem to show fine in windows explorer, and I can playback with Arcsoft, but when I open AnyDVD HD (latest) it just keeps scanning the disc and nothing happens, Disc 3 is fine but 1 and 2 won't load. I have exchanged the Blu-ray and exactly the same thing happens with Disc 1 & 2, 3 is fine again. All other movies I own work fine in the drive. Did I just get unlucky with a few bad discs? Should I try exchanging again? Or could my BD drive be going bad?
