That's not what I meant. I'm using 720x480Noscale, and if I create a full 
screen bitmap that has a border around the screen at about an inch from the 
edges, with lines through the middle vertically and horizontally plus a 
circle in the middle (using Via's windows drivers as a reference), the 
openchrome drivers display the circle as an oval (too narrow) with the border 
to the right is almost 2 inches from the edge (this being on a 26" TV). I'd 
like to find a way to get the openchrome drivers to produce the same visual 
in sizing as the Via drivers do in windows (with full overscan).

I assume the modeline that is being used for the NTSC resolution needs 
tweaking, but I don't know where to start. xvidtune just gives me a garbled 
display.
