The Dark Knight's 2.5 million number, showering viewers with that incredibly high bitrate audio and video (other than some pleading for more low end thump, we haven't heard any complaints.) The downside for a few, including one Crunchgear editor, is that the movie shipped with a new version of BD+ encryption and has had trouble playing on certain Blu-ray players, including the BD-UP5000, BD-C5500, as well as several Pioneer units (fixed after a firmware update.) Some owners have found a way around the issues for the BD-C5500, but there's no word when an update to take care of things completely may be incoming. If you're wondering how much time the extra DRM bought Fox & co. before the BDRips started floating around, DVDFab claimed to break it the same day the movie launched, while Slysoft's AnyDVD HD has offered compatibility with some, if not all, region releases the day after. So much for that ten year prediction.
