Technical Question About Cable TV

I have cable TV, telephone and Internet here. All working perfectly.

I also suck the terrestial channels off the incoming NTL TV feed, so that I can watch bbc/itv without going thru the pace box - I can watch TV either thru the pace box or the terrestial feed no problem. That arrangement works fine too.

I have put a splitter on the incoming feed to the TV, and run the terrestial signal off to another TV. Works perfectly.

Here's my problem...

What I want to do is split the signal again so as to provide the terrestial feed into my PC TV card. There shouldn't be any reason why that won't work. However the TV and PC are on opposite sides of the house (the PC is in my study). So to make this happen I would have to run a TV cable across the house from the TV to the PC.

The TV is fed from a 2nd wallbox immediately behind the TV.

As it happens the PC Internet feed has its own identical wallbox within 24in of the PC.

What would truly be wonderful would be if I could take the TV signal off that wallbox and stuff it into the PC TV card. Easy peasy lemon squeezy to run that short piece of cable.

Tried splitting the cable modem feed which comes off the PC wallbox, but it appeared to drop the signal to the cable modem (didn't bother seeing if the TV signal was okay, the PC has to have its Internet feed). So that doesn't look like a runner (presumably the cable modem is running a different set of frequencies to the TV?).

So my question is, is it likely that the wallbox in my study has the necessary TV signal on its output ports? If so then with the right cable surely I could pick off that signal to feed the TV card in my PC?

The wallboxes on either side of the house are identical. Both have 2 F-type sockets on the bottom. I had assumed that both would be carrying the same signals into the house and it is the box that is connected to the wallbox that picks off the right signals.

And what are the 2 sockets on these wallboxes? There is only 1 cable plugged into either wallbox. Are these sockets paralleled up? Just maybe I could try hooking the PC TV signal from the 2nd socket on the wallbox, leaving the Internet socket alone?

I'm obviously stuffed if NTL configure different signals to different boxes. That sounds a bit unlikely to be honest, but it could be the way it is set up. I just don't know what is on the NTL side of the box.

(BTW, I'm a qualified electronics engineer so a technology explanation wouldn't fall on deaf ears - you probably don't have to spell answers out in braille!).

Thanks in anticipation.
