I haven't looked at this for a few months, but the only way I could
get H.264 encoded video that would play on my ipod was to use the x264
commandline tool with the following options:

x264 --bitrate 600 --no-cabac --analyse p8x8,b8x8 --vbv-bufsize 2000
--vbv-maxrate 768 --me umh --progress --no-psnr --level 1.3 --fps $fps
--stats filename.stats --pass 1 -o filename.mp4 filename.fifo 320x240

Using mencoder to resize, deinterlace and frameserve the original video.

Using the same options in mencoder or ffmpeg never worked correctly -
looking at the resultant mp4 file with MP4Box always showed an odd fps
and the ipod would refuse to play it.
