Hi-def DVD security is bypassed

The encryption on high-definition DVDs has been bypassed, the consortium backing the copy protection system on discs has confirmed.

At the end of last year a hacker claimed he had defeated the protection on a number of HD-DVD titles, leading to fears the entire system was broken.

But the Advanced Access Content System (AACS) Licensing Authority has said the breach is limited.

"It does not represent an attack on the AACS system itself," the group said.

The AACS group has admitted that a hacker had managed to decrypt some discs and other people were now able to make copies of certain titles. more
