I have a few Blurays that offer free digital copies with the movie and I am trying to get them on my new Droid. I am starting with the Dark Knight but have not been successful. I downloaded the movie to Itunes and put in the verification code and then dragged the file from my Itunes to the SD card of my phone. I have tried every player in the Market Place but they keep saying " There was an unknown error with the video" The file name is "The Dark Knight.m4v" My friend hooked up his Ipod did the same thing and had no problems with playback. Am I missing something here?
