Good: this tells us that you are using the nvidia driver with output 
auto-selected. No errors reported so Xorg is happy.

Arrgh!...Late at night brain fade. I meant to ask you to do:

ls -al /usr/lib/*nvidia*

You should see something like this (unless the legacy drivers do really 
weird stuff!):



[root at tor1 lib]# ls -al /usr/lib/*idia*

Well *that* shows things are working. That would not run at all with a 
broken setup.

SUCCESS!

No I meant this one:


http://us.download.nvidia.com/XFree86/Linux-x86/173.14.27/README/index.html

There is a copy installed in /usr/share/docs/NVIDIA_GLX.... with a sub 
directory html, with the same content as the URL above.
You want to read Chapter 16.

Note that that chapter deals with direct tv out, not output through a 
modulator. Modulators usually use the VGA output. In your case, I 
presume that the modulator is actually being used to change the type of 
connection...from whatever to coax(?).

You need to make changes to xorg.conf to tell the driver which type of 
screen it is talking to, etc. and you might then be able to ditch the 
modulator.

But if your output is reasonable, you could just as easily continue to 
use what you have.

> The server seems to work in every other way so doesn't that make it time to get TV out? I mean, I do have monitor out and it does record programs on my ATSC card, etc.

YES! It is now time to get to work on TV out. Since you had never said 
so, I had presumed you were using a monitor directly, not the TV out.

Thanks again.
