Check out Jon Healy's coverage (LA Times blogs) of the Fox / Apple iTunes deal regarding downloading Fox movies. Fox has been in the lead on Blu-ray BD+ and their implicit endorsement of Apple's FairPlay DRM should come as no surprise.
Today, the Financial Times reported that 20th Century Fox's home video unit, Fox Home Entertainment, had agreed to offer new titles for rent through Apple's iTunes store and sell DVDs with an extra copy of the movie locked in Apple's proprietary FairPlay DRM. If the latter proves to be true (no mention of it in the NYT piece), it means the movie industry may be on its way to the same DRM incompatibility problem that has vexed the music industry....
The movie industry has pretty much stuck to uniform electronic locks on each new packaged format: Macrovision on VHS, CSS on DVD, AACS on HD DVD and AACS and BD+ on Blu-ray. Downloads have attracted a greater variety of DRMs, but the major studios have rallied around Windows Media DRM as the lock of choice for rentals. The only significant variation is in permanent downloads, where Disney (for all releases), MGM and Paramount (for just library titles) have embraced Apple's FairPlay in addition to Windows Media DRM and, for burnable downloads, CSS.
Healy says that CSS is still in the mix because the studios think that even broken copy protection is better than no copy protection.
Why anyone persists with CSS is beyond me. Even before it was actually used to protected DVDs, it was clear to all but the most casual observers that CSS was DOA. And so it was.
