Yan,
I tried adjusting the modeline by changing the columns to get the image 
to move on the screen, and I also tried adjusting the overscan as well.  
Oddly none of this has any effect on the image on the TV screen....  I'm 
pasting the relevant sections from my xorg.conf below in case it helps 
anyone help me.

 Section "Monitor"
    Identifier  "Monitor0"
    Option "DPMS"
#Modeline "640x480"   12.700   640 656 744 808   480 492 502 528  -hsync 
-vsync Interlace
Modeline "640x480NTSC"   12.700   700 656 744 808   520 492 502 528  
-hsync -vsync Interlace

Notice that in the ATI driver section I have the TV options section 
commented out.  At first I thought these were somehow overriding my 
manual modeline.  However, I get the exact same image with or without 
those options commented :(
