Have registered both Itunes and Ultraviolet digital copies. In short, no it is not a rental, it is owned in a registered ultraviolet account, , it is then redeemed, then can be downloaded thru Flixter to be watched offline (I believe) or thru Vudu on a device that has it (dvd player, xbox, android, ipad or other device that has vudu-connected online). I hope this helps a little bit.
I got the DVD+Digital Copy, my problem is, The code on iTunes says it's not a valid code. Was there suppose to be a separate CD? The code I'm using is the black paper that's inside the DVD cover that has vudu at the top. Is that the code for itunes too, because that is the only code I see. Anyone else having this problem or has solved it?
If you buy it through Amazon you get the amazon Rental so if you wanted to watch it right away you can. However when you get the actual copy in the mail you get the extra digital copy that can be iTunes or the Ultraviolet copy someone has said that you can redeem both the Ultraviolet copy and the iTunes. I have yet to try that and see if I can get the ultraviolet one to since the code that you receive is supposed to be for only one version. So yes there is the rental through amazon but it isn't true thats the only digital copy you get. Edit. I have now tested it and you can redeem both iTunes and Ultraviolet copy I now have both.
I purchased the BluRay 2 disc combo pack and it gives you a code for either itunes or Ultra Violet. I entered the code into itunes and immediately was able to download an HD version, a regular version, and special features. No going through Ultraviolet or their nonsense.
