Thank you. According to the nvidia readme, this is only necessary if
not auto detected and not NTSC. However I tried your suggestion anyway
but it had no effect as I use NTSC and the SVideo was properly detected.
Other fiddling around has produced better results, although still not as
good as SVideo direct from my DirecTV receiver. I used the app at
http://sh.nu/nvidia/gtf.php to calculate a modeline for 640x480 with a
vertical refresh of 59.94. I used 59.94 as it seemed to be the rate of
choice in many xorg.conf file examples I found via Google. Then I
installed nvtv to further tweak my settings. This command *almost*
works for me 'nvtv -t -r 640,480 -s Huge -S NTSC'. The picture is just
a little "big". Running the nvtv GUI and shifting the horizontal
placement by '2' makes it almost perfect. There is probably 1 or 2
lines outside of the viewing area on both the right and left sides. I
wish I knew how to do this on the command line (if it's even possible).
So overall, the picture is pretty good. I suspect I may have hit the
maximum capabilities of my GeForce2 card. Can anyone tell me if the
SVideo Out quality of newer cards is better? Or should I just get one
of the VGA to component adapters to get good quality? Or maybe a
combination of both would really take advantage of my widescreen TV?
Now all I can get is the standard 4:3 aspect ratio. I just don't want
to spend the money unless I know it will really make a difference.
