Thanks for the reply!

I have tried using the expand filter, e.g.

mplayer.exe -vo direct3d "path\to\my\video" -vf dsize=300:300,expand:300x300 -
geometry 1920x1080+0+0

But the result is the same. The video still zooms to fill the windows (while 
maintaining aspect ratio), instead of displaying at my custom size. 

I also tried using the -nozoom flag, and playing with the -scale filter. But no 
joy. Do you have any other ideas? Thanks!
