Has anyone found a usable way to play MJPEG video files on the N800 yet? I'd sure like to be able to plug in the SD card from my camera and play back the movies on the bigger screen of the N800.

I've tried mplayer, and it seems to think that it supports MJPEG, but I haven't found an MJPEG avi file that it can play successfully yet, even at 320 x 240 (mostly it freezes on the first frame and just continues to play the sound).

mplayer requires ffmpeg compiled with mjpeg support to play mjpeg files. I don't know what the codec situation on the N800 is, so I can't really comment on more than that.
