<pre wrap="">Video looks great on the computer monitor but has tearing, and is
blotchy on the TV over S-Video. Any ideas?
I use the clone option on xorg.conf and I would assume that all
attributes would apply equally to the CRT and the TV. Here is my
xorg.conf and .nvidia-settings-rc.

Hi<br>
<br>
I suspect that your graphics card is using the vertical sync rate of
the monitor output to swap frames rather than the sync rate of your TV.
However, if you change your card to use the sync rate of your TV then
you may experience tearing on your monitor instead. Here's a snippet of
my xorg.conf that uses a TV without any tearing:<br>
<br>
Option "TransparentIndex" "0"<br>
Option "ConnectedMonitor" "TV"<b><br>
Option "UseDisplayDevice" "TV"<br>
</b> Option "TVStandard" "PAL-I"<br>
Option "TVOutFormat" "SVIDEO"<br>
<br>
Have fun<br>
<br>
Paul
