I'm not so sure mpc respects the aspect ratio values recorded in the files 
anyway.

Obviously. That's the whole point. Try some combination of 
mencoder -lavcopts aspect=3.0 -aspect 3.0 (or 3/1).
It depends on your locale if the decimals are separated by . or ,.
In the latter case you'll probably want to use 3/1 (or 16/9 or whatever) 
instead as , is used to separate some other things in mencoder/mplayer and 
it might get a bit confusing.

If you want the actual resolution to be different (most players completely 
ignore the aspect ratio info in the file) then use -vf scale=x:y.
