Ask Arpi but not me - he is original author of vo_mga.
Mplayer's documentation documents -screenwidth, -screenheight keys for that
but vo_mga uses -x, -y for that (which were introduced as user defined prescaling).

GUI is not compatible with fullscreen plugins: fbdev, mga, vesa
simply because that they are non colorkey ones and there impossible
to implement OVERLAYed (by windows) video output.

Framebuffer like a VESA - stupid thing which doesn't use HW acceleration.
(Maybe in Linux-2.6 when there will be implemented some video extensions
for framebuffers).
-fs options doesn't work there simpy because nobody implement SWScaling
in this vo_driver.

I'm watching DVD on radeonfb through -vo fbdev (I have 800x600 at 32 mode)
and have no problem with my radeonfb.
I use such script:
#!/bin/sh
fbset -fb /dev/fb0 -xres 800 -yres 600 -depth 32 -vxres 800 -vyres 600 -left 80 -right 0 -upper 20 -lower 0 -laced false -pixclock 30512
