I just bought a used Nintendo GameCube and PS2, and a new Vdigi VD-Z3 VGA transcoder to hook up to my CRT monitor. The VD-Z3 only allows for a single device component connection. I'm largey illiterate when it comes to cables, but can I split the component cables so I can hook up both the Gamecube and PS2 to the transcoder at the same time?
