If avi is ok, then simply try
mencoder input.file
-oac mp3lame -lameopts br=112:cbr                                    
// convert audio to mp3
-vf scale=320:-10                                                     
                   // rescale your video as needed
-ovc lavc -lavcopts vcodec=mpeg4                                      
    // convert to mpeg4-video
-o target.avi                                                         
                          // output file

Does that work? This is the most basic form of mpeg4 MEncoder will produce.
If it works for you, you can tweak this in a thousand ways to best
match your needs.
