From the BDA site:

"Companies participating in the Board of Directors are active participants of the format creation and key BDA activities ... The board sets an overall strategy and approves key issues."
(http://www.blu-raydisc.com/en/association/membership/MembershipLevels.html)

From the Apple press release announcing their participation:

"The Blu-ray Disc Association (BDA) is responsible for establishing format standards and promoting and further developing business opportunities for Blu-ray Disc"
(http://www.apple.com/pr/library/2005/mar/10blu-ray.html)

It would seem Apple's participation in the BDA is limited to formats and advocacy. Not licensing terms.

"Apple famously refuses to put a Blu-ray drive in its Macs, as Jobs prefers to send people towards iTunes to download their entertainment"

The only explanation we've heard from Apple on the lack of Blu-ray is Jobs saying licensing it from Sony is a "bag of hurt" (http://www.google.com/search?q=jobs+blu-ray+bag+of+hurt). Yet another Sony technology killed by licensing.

The WOPR doesn't count as prior art?
