I'll just add...I have an older model (PCI) Hauppauge card. You'll need an open PCIe slot for that card.
You need the set-top box in order to receive the channels that you normally would receive via cable TV.
When I connect to just the cable wire...I get the basic cable channels up to 125...the card is limited to those 125.
If I want to view a channel that goes beyond that, I must use the cable box.
Your cable provider will rent you an extra box (mine is $3 a month). Using this enables me to view/capture from all channels I've subscribed to, including all those above the 125 limit.
If I try to use just one cable box to feed both the video card and the TV...the output to the video card will be the same as what is output to the TV screen. Hence, the need for the second cable box.
I have a system very similar to the one linked to...I used this for TV capture via the card until I acquired a newer system. No problems at all.
When you install your card, you may not have any sound initially. If so, this will be because the sound volume may be muted initially...changing the volume control setting in XP will remedy that.
