You will want to use the SCART connection if possible. You'll need a SCART plug at one end of a lead that has the phono of s-video type plugs at the other end (s-video is picture only so you also need to plug in sound). From there you shuould have enough adaptors to connect your PC TV and sound cards.

You could use a more basic analogue TV card relying on a standard RF (co-axial) type aerial lead, but the picture quality will be that much worse.

As for the remote unit, PACE boxes don't use standard IR but IRDA. Thus a standard IR remote controller cannot work. Have a look for products called "digi-eye" or "red-eye". These may be compatible (but check before you buy).
