The codecs used in that file and the one I suggested are the same,
however it has downsized the video to 320x240 and 600kb/s . A slightly
modified version of the conversion command should give you something
similar:

ffmpeg -i source.avi -b 600000 -s qvga -r 29.97 -acodec libfaac
-vcodec mpeg4 out.mp4
