The DRM copy protection is so new and so heavy that a lot of players can't play the disc because the player thinks it's a bootleg. And this is AFTER doing firmware updates. There have been reports - though not as many - of people having the same problem with the Alien Quad BD set.
So the bottom line is that Fox is trying so hard to combat piracy that people are resorting TO piracy just to be able to see the movie they can't see because of Fox's efforts.
