Are you sure that you have the latest DivX on your windows-machine? 
(Download and install the latest DivX stuff from <http://www.divx.com/>)

I use the "lavc" codec, this requires ffmpeg:s libavcodec

1. Get a CVS-snapshot of ffmpeg, example:
    $ mkdir anoncvs ; cd anoncvs
    $ cvs -d 
:pserver:anonymous at cvs.ffmpeg.sourceforge.net:/cvsroot/ffmpeg login
    $ cvs -z3 
:pserver:anonymous at cvs.ffmpeg.sourceforge.net:/cvsroot/ffmpeg co ffmpeg

2. Copy the "libavcodec" directory contents into the "libavcodec" 
directory that the mplayer source-distribution has.

3. Configure as usual, check for "#define USE_LIBAVCODEC 1" in config.h


No 2-pass coding should be needed, it just slows things down. Here is 
how I produce DivX4 movies:

$ mencoder
     -ovc lavc \
     -lavcopts vcodec=mpeg4:vbitrate=1200:vhq:vme=5:vqmin=2 \
     -oac mp3lame \
     -lameopts br=320:q=0:vbr=2:mode=1 \
     -vop scale=560:448 -sws 2 \
     -dvd 1 \
     -o outfile.avi
