It should have been the entertainment industry's best-kept secret. However, in February a hacker known only as Arnezami found a key to the encryption system protecting the latest high-definition DVDs against pirates and published it online - just three months or so after the new players went on sale.

To make matters worse, other hackers soon discovered that, in some DVD players, by disconnecting a chip inside the machines they could circumvent their encryption system entirely.
