I've have a quick write up on how I did this to my new
3g nano.  It is here -> http://blog.webhounds.net/?p=6
It basically outlines that I've had great results with

/usr/bin/ffmpeg -i %DIR%/%FILE% -f mp4
-vcodec mpeg4-b 1200kb -g 300 -acodec aac
-ar 44100 -ab 192 -s 320240  -aspect 4:3
/video/ipod/%TITLE%-%SUBTITLE%.mp4?
