Sorry, didn't realize you were using the TV-out; made the assumption you 
were running a VGA or DVI cable.  (don't know *why* I assumed that, just 
did.)  You won't get any EDID information via the tv-out.

For the tv-out, nvidia cards seem to offer only the classic 4:3 modes (at 
least with an s-video cable, not sure about component)... 1024x768, 800x600, 
640x480, and after that who cares.


You should read this document; it has all the nitty gritty, direct from 
nvidia:

But back to your question as to what modes will work with your TV, I see no 
other option than to simply try a few and see what works.  (Might want to 
switch your TV standard from HD576i to either HD780p or HD780i , btw.)


I'd also **highly** recommended that you install SSH before mucking about, 
so that you can get in and change things if you're "blind".  That way if 
something doesn't work, you can change it back.  (Also backup your good 
xorg.conf file before messing with it!)
