You can do it with just mencoder too. 

mencoder -of mpeg -vf scale=720:576 -ovc lavc -lavcopts 
vcodec=mpeg2video:mbd=2:keyint=25:vrc_minrate=600:vbitrate=2500 -oac lavc -af 
lavcresample=44100 -srate44100 -mpegopts format=mpeg2 infile.avi -o 
outfile.mpg

Not sure about all the settings in that, it's a while since I used it.  The 
bitrates above may or may not be correct.

I'd strongly suggest anyone using mplayer/mencoder read the mplayer and 
mencoder users list linked from the mplayer home page.
