Output. You'd probably have to buy a TV Tuner card for the XpressPort on you laptop and then find a way to hook up an RCA cable to that. And no, it would not be HD.
Hmmmm my friend said that the 1394 4-circuit alpha connector would do it,
That is a new language to me? i dont have a clue what that is but aparently my computer has one :S
1394 is also known as Fire Wire, it's an input/output similar to USB only it's a little faster. It's possible I guess, but I have no clue what adapters you would need or how you would go about doing it.
