My prototype worked with 'Option "TVOverScan" "0.5"' in the Device
section of xorg.conf. My new hardware is unaffected by any value of
TVOverScan, even 1.0. (TV CRT with SVIDEO input)
I probably have a little different driver configuration than most in
that I have nvidia drivers disabled in the hardware driver section but
they are being loaded by xorg.conf. I don't really understand this, I
just know that they are loaded by xorg and that the computer will not
boot if I enable them in the nvidia control window. I think there is a
conflict between the nvidia driver and the air2pc cards.
TVOverScan should work. I have seen it work, just not with this
hardware. I don't know what to do. This is the last problem in the
system that I know of. Everything else is working. I need to get the
picture screen filled by the output.
Note, this is not actually a Myth thing as the normal X-windows doesn't
fill the CRT but I though there might be some helpful folks on this list.
