I'm thinking about buying a panasonic tv to play my xbox 360 on. At circuit city its model number CT26WX15 (I can't post links yet) My question is the tv specifically says 1080i and 480p, but will it scale down to 720p which what the xbox does? Or would it go down to 480p? If I'm going to spend money I want to get whatever will work the best but it seems like most conventional box sets seem to do 1080i. any input would be greatly appreciated.
