Thanks for posting that. 

Although I see nothing significantly different. In other words, other 
than the changes to NTSC, and using svideo (which I do not have, just 
composite), then it looks essentially the same in the lines that the web 
page IO referenced told me to change..

I freely admit however, I am no expert on the format of this file. 

For example, to me it seems as though you have 2 screens set-up, but are 
currently using the Acer LCD, not the TV.

There are other differences, but I don't know what is significant, and 
also what might be because yours is xorg.conf and mine is XF86Config-4.
