I'm looking to set up my NTL box in another room. I've bought a splitter and ripped out the old broadband cable from outside the house (as I don't need it anymore) and used this for the cable to the other room.

Now, when I put a plug on the end of the coax and screw it into my NTL box, all the speakers buzz and the screen goes wavy. Now if I take the plug off the end of the coax and just shove it in the back of the box, I get no buzzing but some of the channels don't work. The signal seems to suffer. There is no waveyness either.

So, I'm in a bit of a situation.

A: I listen to a humming sound and get all my channels

or

B: Have fewer channels and no buzz.

Does anyone know why this happens. Is there a difference between the coax they use for broadband and cable tv or is it the same.

I know I can get NTL down to do it but there is a 2-3 week wait, I've been let down 4 times in the past by engineer no shows and I don't want to pay £25 to get it done after the world cup is finished.

I really appreciate your help
