Software scaling is how I traditionally solve this problem. :)  But I'd
like to do it without, since this is a solution intended for lower power
machines.

If there's actually no way to do this with any combination of expand and
dsize, I may look at patching vf_expand.  One possible (although not
very elegant) solution is to obtain the video's resolution and display
aspect first (using -identify or some other means), do the calculations,
and then load MPlayer again with explicit dimensions.  I'd rather see
vf_expand get this feature though. :)

Thanks,
Jason.
