    Anyways, the whole purpose of buying HD media is for the HD. If it's then downscaled right back to just-slight-above DVD quality, I think people are going to be, pardon my French, pretty fucking pissed. Especially the early adopters who have the highest chance of getting screwed over.

    Well, kicking down the front door of the central HDCP bureau and storming it with torches and pitchworks to get the master key is just another kind of brute force attack, no ?-)
