X configs are a bit complicated if you need to customise them.  We
need a bit more information.  First, are you using the accelerated
Nvidia drivers for your card (and if so what version), or the open
source nv drivers, or even the Vesa drivers?  Second, what is your
current /etc/X11/xorg.conf file?  Have you modified it at all?

Below is the XF86Config-4 file I used to use with my old CRT TV and
S-Video under KnoppMyth.  It should be similar to what you want for
your xorg.conf file for TV output, but TV output is 720x576 - it would
need to be adjusted to do 1024x768.  I am not sure if an old CRT will
do 1024x768 anyway - I would have thought that resolution was a bit
more than it could cope with and even if it worked, everything would
be too small and fuzzy.

Also, an 9500 GT card will do VDPAU acceleration and for that you need
to be using Nvidia driver version 180 (reasonably stable) or above
(reportedly less stable, but I have not tried 185 or 190).
