Just to state this out right UltraViolet Digital Copy is not an actual copy, It is NOT compatible with ITunes This is the ability to stream the Movies, not Download them. And Frankly It's false advertising.
Really? That's odd, because I was able to download an UltraViolet copy of The Girl with the Dragon Tattoo onto my phone just fine a few months ago, and what's even weirder is I even downloaded a copy to my computer too. Research before posting next time. Make sure that what you're about to post is true, you get less egg on your face, it's happened to me far too many times than I would like. I was talking to my friend many years ago, and he talked about living in Georgia in the past, and I knew he was lying about where he had lived because he told me he lived somewhere else before, I called him on it and said "That's not what you said before! You said you lived in Atalanta!". Atalanta is a city in the state of Georgia, of course I know that NOW, but it hadn't occurred to me before I said it. He informed me about my faux pas, and made fun of me for weeks afterwards. Be careful.
What Cat said about the UltraViolet Digital Copy is true. It started with the seventh HP film. I tried to download the digital copy and found out that I had to "register" and provide my information in order to access a digital copy. I couldn't get it through iTunes like the previous HP films.
