Hitachi 60V500 Input questions  

I could not find an answer to this on the forum, so could someone tell me if both component inputs on this tv support 480i to 1080i? I was looking at the samsung dlp but since one of the inputs i read only supports 480i/480p, and the other is 480p/720p, this is a big problem since i have a gamecube xbox and ps2 all hooked up with component cables to switcher, and the component out cable have to go into one input, the problem is some xbox games support 720p, xbox live only supports 480i, and if the input does not allow from 480i to 720p I would have to switch inputs all the time.
