Errr, what kind of movies?
Via the SD card, you should be able to just open the movie file (mp4??) and play it in your media player.
Hulu is still blocked to my knowledge, but any unblocked flash site, so long as you have flash installed and a supporting browser, you should be fine - even though the phone will get hot.
There are programs to convert videos to mobile format and there are a few formats that should be handled by the D2 (not sure which ones exactly though)
