An article in yesterday's WSJ all but confirmed that that latest Fox releases are protected by BD+, a second, virtual machine based security layer used by Blu-ray and not HD-DVD discs.
The WSJ article also noted that the AACS licensing authority has released a new key for AACS, the renewable encryption and authentication technology on both Blu-ray and HD-DVD discs. However, no press release has yet been posted on the AACS LA web site and neither Google News nor Yahoo could locate it elsewhere.
With respect to BD+, the WSJ article said:
Steve Feldstein, a spokesman for Twentieth Century Fox Home Entertainment, said both HD-DVD and Blu-ray players occasionally have needed updates to play new discs, and urged customers to monitor manufacturer Web sites that distribute the fixes, known as firmware updates. "When these sort of glitches happen, they're resolved in...a week or two, once people realize they do need to use the firmware upgrades," he said.
Mr. Feldstein declined to confirm that BD+ was on the new discs, saying doing so would be an open invitation to hackers. He also said BD+ wasn't the cause of the playback problems.
