Samsung Calibration Help
 

So basically my Xbox 360 looks like dick thru my Samsung LN40A450. I've done some research on it, and it looks like it's automatically going to PC mode on my tv, because it won't let me adjust the values for color, sharpness, or tint (they are grayed out.) The value for color is 55 and is off, whereas when I am connected to my cable box the value is 50 and is fine. Simple solution, change it to 50, right? Does anyone know how I can get this option to unlock from its grayed out state? Any help would be awesome...

NM I think... I had to change the settings on my Xbox from auto scale to 720p... Just need a calibration disk now to finish it off.
