I use these parameters to do it:

[darose@darsys9 ~]$ cat bin/avi2ipod.sh
#!/bin/bash
#
# courtesy of https://help.ubuntu.com/community/iPodVideoEncoding
# except changed to use vcodec libxvid instead of mpeg4
ffmpeg -i "$1" -f mp4 -vcodec libxvid -maxrate 1000k -b 700k -qmin 3 
-qmax 5 -bufsize 4096 -g 300 -acodec libfaac -ab 192k -s 320x240 -aspect 
4:3 "$2"

e.g.:

avi2ipod.sh SomeMovie.avi SomeMovie.mp4

HTH,
