those are for component cables. You are going to need those for progressive scan which GoW2 has in 480P. Unforutnetly most games dont have progressive scan as an option. I havent played my PS2 on an HD tv but I have on an HD monitor and it looks like crap. I hope that isnt the same with an HDTV bc Im planning on getting one myselfOh, btw....
My hd-ready tv has some weird inputs in the back that say Y, Pb and Pr.
