Well, I don't know how HDCP works (and I'm not really interested in HD at the moment) so I'm surely wrong, but the above link gave me the impression that there is some kind of end-to-end encryption, and every device in the chain has to cooperate if you want to see the full resolution, so if it is possible to keep it encrypted from the dvd to the tv/monitor it will surely be possible to do the same from the broadcaster to the tv/monitor.
