I think I read on the web that there could be locked content on the next generation disks. A particular interest of mine is film music soundtracks. However, I know that this is a minority interest for most that buy dvds etc. Would it be possible for the scores of movies to be unlocked on HD-DVD and Bluray (obviously by paying an extra fee). It would be a nice earner for the film studios. Its pretty unusual to get an isolated score on dvds (is that because of commercial reasons ie so as not to hurt their cd score sales?), but it would be great if this was a standard unlockable feature on next generation disks - pay a bit extra for the scores you love! I've always thought that the soundtracks on cds never really worked, as they are almost always editted, and usually in stereo. I think there would be quite a market for film score lovers if we could have the score unlockable in high resolution audio. I get goose pimples just thinking about it - the whole score, in fantastic fidelity, in surround sound... I know that I'd buy dozens and dozens of disks.
