Also the encryption on the next generation discs will not be "static" like CSS. That means that if someone manages to break it, the studios can change it by putting updates on newer discs. One of the ideas they have is that if someone manages to break the encryption for say Batman Begins or whatever, and uses Memorex HD or BluRay media, they can put out an update on the next disc that gets released that invalidates that media for all the drives. Hence, anything you have on Memorex, for example, will no longer play. As you can see, the next generation discs will go WELL beyond simple encryption for protection of content. If they wanted to, they could invalidate your original movie that you bought and paid for, as well. I for one will not embrace that technology as I believe it has far too many restrictions and possibilities for future restrictions. There's nothing stopping them from switching to a pay for play model down the road.
