Query: Beware of the Ultraviolet Digital Copy

This DVD does not come with a real Digital Copy of the movie. It provides access to a Cloud version of the movie which requires you to be connected to a Wi-Fi network. In other words, it is not compatible with Macs, iTunes nor an iPad / iPhone when you are in the car, bus, plane, etc. For more information, I recommend you view some of the comments from the Green Lantern DVD release [...]. In my opinion, Ultraviolet Digital Copy is blatantly misleading and I refuse to purchase any more DVDs that don't come with a standard Digital Copy version.
