Disney Dvd Player Why Won't The Disney Movie "Up" Play In My DVD Player?

Why won't the Disney movie "Up" play in my DVD player? - disney dvd player

Sun bought the movie and not play. Can I play not on the menu and the movie, but the movie. I'm playing on the computer, and a different player, but I think I should rearrange the electronics in my house, just to read a Disney movie. My drive does not help, and other films like new. I just watched GI Joe and transformers2 no problem. Disney is a certain form of new and unusual that you can not see my readers?
