OK, so now I have some of my iTunes music on my Atrix, but I must be blind as a bat because I cannot find the means to download some movies onto my Atrix. What am I not seeing?
If you enable Mass Storage Mode via USB cable, you will be able to drag & drop the movie files to your Atrix. It's the same process you'd use if you wanted to drag & drop files without using Desktop Manager on a Blackberry.
