Still be excited with my new Nexus 7, the first Android tablet for me. After three-day experience, here I'd like to share some movie playback tips on the new Nexus 7 (2013 version). The almost same with yours.

Own some personal avi, vob, mkv files, I can freely transfer them to the Nexus 7 2nd as long as changed the video format to mp4 in advance. Of course, if you 've downloaded some video player app, you can play videos on new nexus 7 in extended format.
