Some movie cases are very deceiving and don't give you very much information on the type of digital download they're giving you. If you find yourself in this situation, it never hurts to contact the vendor and ask for an iTunes code instead. What am I supposed to do with a movie that I can't play without a player that isn't supported by anything else? I purposely buy movies that have digital copies in order to be able to play them from all my devices and from iTunes. Needless to say I wasn't very happy about this. I recently bought a movie that made me download the Flixster software in order to play it. If you're digital copy requires you to log in to some other kind of service to redeem your movie it may get a bit complicated. Just redeem your code and your digital copy should automagically show up in iTunes, and Movies in the Cloud will let you re-download it across all your devices for download. If you open up your Blu-Ray or DVD and the digital copy consists of an iTunes code to redeem an iTunes copy of the movie, you're golden. The non-simple answer is that it depends on how the company distributing the movie decided to provide a digital copy.

How and when Movies in the Cloud works with Digital Copies has been the source of some confusion.
