Updated!
I tried TV with my main computer
AMD 6400+ X2
4GB RAM
Nvidia 9600 GT 513DDR3 PCIE overclock
Vista home premium
I was really surprised THE PICTURE GOT EVEN BETTER!. With Ati Windows desktop is flicking but NVIDIA card really made picture stable

Even there was option in resolution menu to use 640x480i SDTV

both cards wont work in dos ..picture came out in welcome screen.
I will take some photo soon and post them
