    This stuff, just like region encoding, is about price-fixing. That's why the security is crap: its only purpose is to prevent the 99.99% of consumers who will never crack even a trivial encryption from recording a TV programme instead of going out and buying the HDDVD of the series later in the year. That keeps the price of those DVD's up and that's all this is about.

    It used to be called "a cartel" and it used to be illegal.
