If you rely on the X server to guess the correct display size, your setup will
be wrong most of the times. Many monitors simply don't report the physical size in the
query. And not all the X server drivers are able to query the monitor.
(If I remember correctly, nv driver doesn't do it, proprietary nvidia
driver does it).
It is always good to physically measure the size of your monitor and put the values
in the X config file.

What do you mean here?
I have a flat monitor with resolution 1280x1024 and aspect ratio 1.25.
The X config file has the correct values for the display size.
Xine shows correctly a 4/3 video in full screen mode with orizontal
black bar. MPlayer needs -monitoraspect 1.25 in order to work
correctly (it doesn't query the X server).
