they cant' stop it. there will be underground projects to play dvd's on linux. xp was said by M$ to be un pirateable. go to any p2p network and find cracks for xp. it's microsoft,. they don;t want people to use linux, definatly not in homes. if they can create some shite about linux being a threat to anti piracy protection, the shit heads that do all this protection crap will listen to them and do what M$ tell them to.
