lmb10164 - I have not attempted a "Digital Copy" Movie on the unit - all of the movies I have played on the unit were "shared" videos encoded in my before mentioned file formats.
1- Im curious - what is the file format of the digital copy movie you want to play?
2- dont worry I have deployed a friend of mine to experiment with her unit and attempt to play a "digital copy" movie (I think its Green Lantern FYI) I can let you know results
3- if the movie is encryped (DRM[digital rights management], Protected etc.) then the unit will not play it.
Ill experiment and update the board when I have more details -
