Gilgamash: My contention has always been the same. Encrypted content that is uncopyable for personal use WITH EASE, and unplayable on anything except proprietary devices will not be successful in the market place. DP as a storage medium is not doomed to fail, per se. There are lots of far less controversial applications that require no encryption. It is obvious to me that with only 15% of the market having access to broadband, the labels will not make any significant effort to release their property to DP, especially with no appreciable number of players available to play the discs.
With ITRU now owned by the new Sony/Phillips consortium, DP will be forced to license their DRM from them; not unlike the way all manufacturers of CDs now license the tech from Phillips.
One thing of which I'm reasonably certain is that Universal will not be involved in manufacturing music players, under the conditions that currently dictate their position from the parent company in France.
