If you dropped $20 on an HD movie from iTunes since they came out yesterday, but have a newer Mac and an older external display, you might not be able to watch it.
That's because iTunes HD movies require that you have an HDCP-compliant external display. High-bandwidth Digital Content Protection is designed to prevent video from being copied as it moves across digital video interfaces. So, as iLounge points out, if you're using a Cinema Display older than Apple's 24-inch LED model (or any older DVI or VGA monitor, basically), you're screwed if you have it hooked up to a newer, HDCP-loving Mac. You just get a black box where the video should be.
It's not the first time HDCP has caused iTunes-related pain. When Apple first started rolling HDCP, they even applied the protections to standard definition content, so a whole bunch of people found out they couldn't play new movies they bought, so Apple wound up pulling back on SD, and everyone forgot about it until yesterday, when you could finally buy HD movies.
One solution iLounge proffers is to transfer the file to one of your older iTunes authorized computers, since Apple doesn't pull the HDCP mojo on them. The other is to play the movie in standard def mode—then it'll play on your monitor, but in crappy standard def. Of course, the irony is, if they just supported HDMI like every other computer company in the world, there'd be more than one external monitor you could use, since HDMI supports HDCP natively. All together now: HDCP sucks. [iLounge]
