Try including:
-ffourcc mp4v

Here are some command line settings that work for me (adapted from 
http://ffmpeg.mplayerhq.hu/faq.html#SEC16):

mencoder "$infile" -vf scale=320:240 -oac faac -faacopts mpeg=4:raw:br=128 -ovc 
lavc -lavcopts 
vcodec=mpeg4:vbitrate=1200:mbd=2:cmp=2:subcmp=2:trell=yes:v4mv=yes:aic=2:vglobal
=1:aglobal=1 -ffourcc mp4v -of lavf -lavfopts 
format=mp4:i_certify_that_my_video_stream_does_not_use_b_frames -o "$outfile"

or

mencoder "$infile" -vf scale=320:240 -oac lavc -ovc lavc -lavcopts 
acodec=aac:abitrate=128:vcodec=mpeg4:vbitrate=1200:mbd=2:cmp=2:subcmp=2:trell=ye
s:v4mv=yes:aic=2:vglobal=1:aglobal=1 -ffourcc mp4v -of lavf -lavfopts 
format=mp4:i_certify_that_my_video_stream_does_not_use_b_frames -o "$outfile"
