I tried this command (with scale=176:144 and -ofps 6), but only MPlayer can play
it. Nokia Multimedia Player, Quicktime Player 7.2 and my cell phone (RealPlayer)
play the audio, but they all just display a blank screen. Th exact command was:

mencoder  -oac lavc -ovc lavc -lavcopts
vcodec=h263p:vbitrate=10:acodec=libamr_nb:abitrate=10200 -of lavf 
-vf scale=176:144 -srate 8000 -af lavcresample=8000,channels=1
-endpos 30 -ofps 6 test.avi -o test.3gp

Where applicable, all apps reported correct information about the codec,
dimensions and frame rate, but they did not play it.

I am using SVN-r24594 on Windows XP.
