Hey, recently I bought an HDTV, and I want to hook my Xbox 360 up to it, but I can't get it to display at 1080p. Is this because I only have component video cables and need HDMI to display at 1080p, or what do you think the problem is? My TV is a Panasonic pz700u 42 inch plasma TV. I have all of the most recent Xbox 360 updates downloaded from live, so that shouldn't be a problem. And my Xbox is from January last year, just in case that has anything to do with it.
