Yes: you can use the video filter "scale".

a command line such as:

mencoder input.avi -vf scale=320:240 -ovc lavc -lavcopts
	vcodec=mpeg4:mbd=2:trell:v4mv:turbo -oac copy -o output.avi

would do the trick, but beware, it is highly suboptimal since it
doesn't do a two pass encode, and it doesn't specify a target bitrate
either (but this depends on your current bitrate and which target size
you are aiming at).

Read the appropriate sections of
http://www.mplayerhq.hu/DOCS/HTML/en/mencoder.html and
http://www.mplayerhq.hu/DOCS/HTML/en/encoding-guide.html to become a
master of MEncoder!
