Hi fellas, I have just bought a panny TH37PE50 plasma and I cannot figure out how to get sound from my ntl set top box to my panny home cinema kit (scht530). as there are no phono sockets on the back of the set top. I phoned ntl and they said I need to buy a scart block with these phono connections on it, Is this correct? If so how do I conect it all up? And which ones do you recommend? Many thanks In advance.
