If you thought you would just pick up a copy of Avatar at midnight on Earth Day, pop it in your BD player and break out the popcorn, you might have been suprised when it had trouble playing. No, there is nothing wrong with the Blu-ray Disc. Avatar will apparently not work on many Blu-ray players without a firmware update. According to a Best Buy service rep this evening, Avatar (in 2D) would not work on 70% of their in-store Blu-ray players before a firmware update. Hold that popcorn. The updates can be made via internet, flash drive or disc. Good news for PS3 owners though, as the system should update itself if needed when the disc is popped in.
