High Definition Content Protection (HDCP)—you can't live with it, but you practically can't buy an HD-capable device anymore without it. While HDCP is typically used in devices like Blu-ray players, HDTVs, HDMI-enabled notebooks, and even the Apple TV in order to keep DRMed content encrypted between points A and B, it appears that Apple's new aluminum MacBook (and presumably the MacBook Pro) are using it to protect iTunes Store media as well.

When my friend John, a high school teacher, attempted to play Hellboy 2 on his classroom's projector with a new aluminum MacBook over lunch, he was denied by the error you see above. John's using a Mini DisplayPort-to-VGA adapter, plugged into a Sanyo projector that is part of his room's Promethean system. Strangely, only some iTunes Store movies appear to be HDCP-aware, as other purchased media like Stargate: Continuum and Heroes season 2 play through the projector just fine.
