I love my Nexus7, BUT, I thought I would be able to transfer my digital download movies (like Up and Toy Story 3) to the tablet for my grandkids to watch.  I was wrong.  I have now discovered that Nexus7 will not play these movies unless they are converted to mp4 and DRM is removed.  I have found two paid PC programs (Aimersoft DRM Media Converter & iSkysoft DRM Removal) that will remove the DRM and convert to mp4 and will allow playing the movies.  This is a long tedious process and I have a lot of digital movies I want to transfer.  Does anyone have any better suggestions?  Is there and app that will allow me to play the original files or convert them for me?  It there any free PC software that will do the job?
