Blu-ray won the HD format wars a bit less than a year ago. Since then Blu-ray has been adding features and updating the specifications for more interactivity and features. Many Blu-ray players are now Internet connected offering interactive features like BD-Live.

Warner Home Video has announced its first BD-Live enabled Blu-ray film is coming. The film is The Dark Knight, the latest Batman film that was the last performance of actor Heath Ledger. I saw the movie at the theater and it was fantastic.
BD-Live features on the disc will include My WB Commentary that allows users to record commentary on the movie and overlay in picture-in-picture style on the film as it plays. The movie will also feature BD-Live community to allow fans to schedule screenings with friends and chat with other viewers as the movie plays. The film will be available on December 9.
