Digitalcopyplus.com is the Disney Digital copy site. Doesn't work like UV codes. You have to pick a player and it will only play on that one. Like iTunes, VUDU or Amazon.
No UV codes can be used on any of the players. Disney codes can only be played on one player. You pick your player when you enter the code a day that is the only this you can ever play it on. Versus UV codes where all your UV movies can be played on any of the series that link to UV like VUDU, flixster, Target and the rest.
Only down side is only being able to play on the one player so you just have to make sure it's the one you use the most. I pick VUDU since I watch my UV movies more on it than the others.
