Plex is a home theater solution... free on home computers but now selling mobile clients like plex for kindle fire... set up a server with media (movies, Tv shows, home movies, music, photos, etc) then use a client (like the 5.99 plex for kindle fire) to access and view media either at home or on the go.
I have been using the kindle fire client quite a lot lately. Very nice for combatting insomnia.
