Over the past few days I've noticed that the option to buy a number of HD movies over iTunes has been made unclickable. These are the same movies that WERE clickable just a week ago. I wanted to buy Shutter Island, but had to purchase it in HD over my iPad, since on my laptop the HD was not an option. I figured when i plugged the iPad to my comp, it would then download the HD version to my computer, but it only downloaded the SD version. Only about a week ago, I did have the option to purchase the HD version on my computer, and now the option has been faded. I just bought the HD version of American Psycho on my computer just a week or two ago, and checked on iTunes again, and the option to buy HD was still applicable. I did notice under the two purchase options it mentioning that your Mac or PC must be HDCP compatible or something along those lines. Any clues?
