If you play a DVD, most DVD players (remotes) allow you to press a button and display the information about the technical details of the picture you are watching. One of these details is the "bitrate" of the video signal. The higher the bitrate, the better the video quality will be. The bitrate will vary from scene to scene, depending on how much detail, color and motion is in each scene. A "superbit" DVD will ususally have elminated all of the extra material on the disc that uses up space that can be used for the actual movie, so the entire capacity of the DVD disc can be allocated to the movie. And, if there is more space allocated for the movie, less compression is needed and a higher bitrate can be allocated for the movie, resulting in more picture detail. "The Fifth Element" is a very good "superbit" DVD, and there are others.
