Right now, MEncoder is not able produce "complete
standards-conforming" .mp4 files. Means: You can try, but don't expect
your device to like the file....
See http://gpac.sf.net for an full-fledged .mp4 muxer (file-creator).

As far, as I understand, this bundled software will allow you to
convert a lot of stuff, including avis, in a fitting format for your
device. Depending on what kind of source of video you have, you might
try converting it directly with that software.
Otherwise you might use MEncoder to convert your video to mpeg4 in avi
and then mux it into .mp4 using this software or gpac.

Hope this helps :)
