Just how do you hook cable up to a TV tuner card?

Building a new system, will include
an ASUS TV tuner card.

Looked at a pic on the net, it's got
an FM in, RF in (both of which look
like the standard cable tv hookup)
and what I think is an S-video in
(round female plug with a number
of holes).

How do you get tv from your cable
tv box into that?

Thanks as always!

I would guess you'd just use a coaxial cable from the cable box's output and connect it to the tuners rf input jack.

Figured it had to be relatively simple

Guess I was confused by the multiple hookups,
and didn't know for sure what "rf" stands for
or what the hookup was for.

What's the advantage of and use for the video-S
round hookup?

It allows you to connect to the S-video out of any video device, ie. Video Camera, DVD Player.

S video would be a higher quality signal. The picture would look clearer with it.
