Hi,

You don't give much detail about what you are doing.
Maybe you can get some help from these notes I made: 
http://www.asdk90.dsl.pipex.com/tf1/tf1.html

They are for making SVCD, but extracting and muxing video
stream for DVD is fairly similar.

I made these notes when I was learning mencoder, and
originally using
an older release, so I know that there are imperfections!
But it does work.

I now create DVD streams without using mplex, basically 
using the command from MPlayer notes:
http://www.mplayerhq.hu/DOCS/HTML-single/en/MPlayer.html#menc-feat-vcd-dvd-all-pal-dvd

i.e.
  mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd
-vf scale=720:576,\
  harddup -srate 48000 -af lavcresample=48000 -lavcopts
vcodec=mpeg2video:\
 
vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=15:acodec=ac3:\
  abitrate=192:aspect=16/9 -ofps 25 \
  -o movie.mpg movie.avi

although I usually need aspect=1.3333 and scale:352:288
