In the coming months I'll be purchasing both an X-Box and Gamecube, and I want to know the best way to hook them up to display them with my system. I can use component cables for both, which are fed to a passive switchbox for my DVD player, PS2, and the two new systems. That component video signal is then fed to an IScan Pro line doubler, which then goes to my projector (NEC LT 150). So is it as simple as connecting the systems like this? I'm just wondering if they are already sending out 480p signals and thus there might be some sort of issue connecting them to my line doubler like that. Thanks for any help.
