I want to hook up my TV (Phillips 32inch Flatscreem CRT) to My PC

PC has a Nvidia 8800GT 

TV has scart and rca and svid 

I have an Svid cable but it doesnt fit the svid on my graphics card???

I have a cable that I can plug into that funny svid but it comes out as 3 rcas (red Blue and Green) Y pb Pt

Whats the best way to get this all hooked up ?

Im not to worreid about the OS side, can sort that out, its just the cable situation
