Ok.. Here is the deal. I have a HD tv and an Xbox. So I bought the advance AV pack for the xbox and connected composite (red,blue,green?) from the AV pack to the TV. Some of the new games support 480p but when I go to change my TV to 480p that setting isn't there. There is only 540p and 1080i? And when I do change it between the settings I do have (540p to 1080i) I really see no difference. And anyone shed some light into this matter. Thanks!
