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
