Get into a terminal and issue this command:
nvidia-settings  -a TVOverSacn[TV-0]=2

You may have to change your device from "TV-0".  Try 'grep "(TV" 
/var/log/Xorg.0.log'  and it may tell you what your device is called.

If you see the picture get very small, change the 2.  I think 10 does 
nothing but I am guessing.  I use 12 as I want more overscan.

If you find something that works, you need to find some where to put it 
to make it permanent.  Check out the posts on TVOverScan not working 
that I started and you will find a variety of opinions on where to put 
it.  I put it in /etc/gdm/Init/Default but that may not be the best 
place.  It worked for me where a majority of the suggestions I got did 
not work.

There is a gui for nvidia-settings with pretty slide levers.  There are 
also a  nice set of instructions that go with it on what to do to make 
them permanent.  However, none of that worked for me.  I am using 
Mythbuntu 8.04
