Same problem, navigating to my external card, drilling down through the directory structure etc...then coping with mplayer's power drain and sometimes wonky behavior. Ditto for using bookmarks in the browser. Launching the browser activates the internet connection, which I then have to shut down to minimize power drain etc etc etc...wasted keystrokes, wasted battery life - just to play an flv file. With flash so central to the tablet's success, a stripped down gui whose sole purpose is to play flash files offline from a preset directory, with minimal power consumption, would be a most useful app.
