Way to use iMac screen for Cable, Xbox, Wii, etc...

[hawk2417]

Is there a way to use my iMac's screen to hook up my cable, Xbox 360, Wii, and other various systems using a TV tuner or something like that? Also, will I be able to use the component cables (HD) for this?

I don't think there's a direct video connection, but you might be able to use something like Elgato to connect...
