I'm looking to play my xbox in 720p but I believe I need a component cable setup to do it. I have a pinnacle pro tuner card and it doesn't have component in nor do any of pinnacles other products. Are there tuner cards out there w/ component in or do I have to go about getting the signal into my PC through some sort of adapter? My CRT has RGB and 2 syncs for input, is that going to mess me up too?
