Old tv with 9600gsp

Hey guys!
I have the 9600gso, and I would like to hook it up to an old tv from 2003. It only has rca inputs and no svideo. My 9600gso came with an svideo to component cable adapter but my tv does not have component. I have a Toshiba DVD Player(i think its toshiba) that i bought in early 08 that has component in and outs. If i hook up my pc to the dvd player and then to the tv will it look good??? Im not sure especially since the resolution is prob low on the tv. I would like to play games on it. Also can i use a rca cable as a component cable, its really he same exact cable...

thanks!
