For some reason, I can't post it on the regular boards, it only lets me search for a topic. When I start up my ps2, and forget to go into the options menu and turn it from 480i to 1080i, I didn't even notice a difference visually. The only thing that I noticed was that the screen shaked and the picture looked cut up on 480i. In 1080i, the visuals looked the same only that the picture didn't shake and didn't get chopped up. I haven't tried playing gt4 with my composite/rca cables yet.
