"...surely you jest...come on scotty"
Well, no not really. If it's very very hard to copy a disc, very few people will do it. If very few people do it, they won't need to warn everyone not to do it. Pretty simple really. And let's be clear, this isn't targetted against scamps giving a copy of a film to a mate, this is targetting people making 1000's of copies to sell for a fiver down the market. Which I don't think anyone here is trying to say is alright. And if you do, please come out and say it soon so we can discredit everything you say from now on.
"Why, oh why, would anyone ever buy screw-ray (tm) when the monkeys that make the discs and the monkeys that make the machine can change the drm any time they want and kill your machine and discs so you can't use them? HELLO!"
Hahaha - that's right. If you don't follow Sony's new world order they will magically write animal porn and goatse all over your favorite movies and make your BluRay player turn into a chicken.
Seriously tho, even if you are guillible enough to believe something like this, what makes you think it isn't the same on HD-DVD? It does have DRM on it you know. Just because it's worse than BluRay's DRM (along with all the other specs) doesn't mean it's not there. Just like HD-DVD's do have region encoding, they just didn't turn it on to appeal to, well, anyone by that stage. HD-DVD and BluRay are pretty similar in what features, DRM, encoding etc. they have. BluRay is just slightly better at all of them.
