I bought a new 50" plasma 720p. I was messing around with my dvd player and switched it to progresive scan and the screen went black and I only had sound. I was playing guitar hero on PS2 and went to switch to progressive and it didn't work. How do you go about recieving a progressive scan signal on these tv. BTW, tv is a 50" Panasonic Plasma TH-50PX60U EDIT: I believe I have it figured out. I guess I need those component cables...the Y and whatever those others are, not hte red, white, and yellows.
