i think for long videos that have been downloaded - to load you've got to wait for it to buffer for a few seconds(let it try to load for 5-10 seconds) and then i think you press "select" or "start", or was it "x" for it to start playing. it does have a bug btw, i think i saved a clip that was 7 minutes long and during the 5 minute or so mark it froze, but whatever, it's still cool.
