The Noosy HDMI Adapter seems to have this limitation;
Do not support the movies that were purchased through iTunes or locked with Apple's Fairplay copy protection scheme.

Does the official Apple HDMI adpator also have this limitation?

I am impressed that the iPhone 4 can do 1080 video. Not actually tried it - yet.
