geekd writes "Once again, DRM only hurts legit content purchasers: 'An unusual glitch has angered some Avatar Blu-ray owners. For these unlucky people, since the disc won't play on their Blu-ray players, their new Avatar DVD serves no real purpose other than to sit idly on the coffee table. ... It appears the main culprit concerning playback issues with Avatar is, ironically, the disc's DRM (digital rights management). ... Even with updated firmware, a lot of Blu-ray players weren't prepared for these security measures. Despite the security problems, bootleggers are having a field day. Pirated copies of Avatar, according to Los Angeles Times, were available as early as January.'" Reader Murpster adds that this problem isn't specific to the Blu-ray version: "Got a regular Avatar DVD and it won't play on either of my DVD players. It will play on one computer DVD drive, if I want to watch it on a 12-inch screen."
