iTunes playback error: garbled image. AVF error: Gen7IntelGVAScheduleAVDCommands, TT err = 5

I can't play rented movies in iTunes, and I'm not sure why. I can play other ripped movies (m4v format) in iTunes, and all VLC movies work fine Any ideas anyone?

I have this exact same error but on a desktop...I haven't found a solution yet either, I did find this though may help you on your laptop? http://www.insanelymac.com/forum/topic/284208-hd4000-garbles-movie-previews-in-itunes/

All it did for me is produce a black screen when trying to play an HD video as in the video doesn't even play.

I was one of the first people to discover this fix. It worked up until 10.8.3 was released. Unfortunately I haven't been able to find a workaround. If I do I'll be sure to post it.
