we just purchased a mitsubishi wt 42311 television, we do not plan on watching regular tv using the hdtv, but we would like to play our xbox 360 using the hdtv, when we hook the 360 up however it says it is playing on 480i or 480p.. is there a way to change the setting or is the tv we have only hdtv ready and therefore not capable of doing this. The xbox 360 we purchased has all the correct cables for the hdtv hook up aswell. thanks guys
