7800gtx svideo

[mikenam]

hi i just got a 7800gtx. I also have a magnavox 15" hdtv w/ svideo and component input. i don't have any component cables so i wanted to hook up my computer using svideo cable. when i hook up the svideo cable to the monitor and change to the channel to s-video i don't get anything. can anybody help me?

also which is better vga, svideo, or component. im assuming component is the best then svideo then vga?

thanks.
