Purchased movies won't play anywhere
Super frustrating when this is supposed to "just work."
So I get the BD combo pack of Titanic, and promptly download the digital copy, extras and all, to the tune of 3.5 gb. Then I decide it might be fun to watch some on my iPad 2 before I fall asleep. When trying to launch it, I get a "cannot open" error. I am somewhat used to this error from other videos so I think fine, will stream it on my iPhone 4. Again, get a "cannot open" error. So I go to my MacBook (10.8.1) and try to play it there on the iTunes (10.7). The extras launch just fine but no movie even though I click on play several times. Okay then, found it in the finder and played it in QuickTime X. No problem playing there. So I try to open it in iTunes again where I get a "this movie requires QuickTime" error. Then, as a last ditch effort, I try my Apple TV. For some reason, again the extras are fine but the movie is a no go.
What the **** is happening here?
