Harry Potter, Macrovision and Economics

markthebrewer writes "Apparantly Warner Home Video have released Harry Potter and the Philosopher's/Sorcerer's Stone without any of the usual Macrovision copy-protection systems. Looks like its just a trial, but someone's done the maths and decided it may be cheaper not to copy-protect videos after all. Find the full article in the New Scientist." There is certainly something desperate about macrovisions response to this development. Does anyone see macrovision as a real barrier to copying anymore? What a bunch of snake oil salesmen these people are. In related news, I'm marketing my own personal copy protection device.
