I've got chorus sagem itd 4400 box in the living room connected to the tv. however, i can't get a signal for a second tv off the second fplug connection on the box not even a analogue signal as there seems to be interference on each channel. this is probably scrambled from the box. just wondering where i can purchase one of these boxes. if i did get one would i have to programme the box as well or can that be done? desperate I.T. guy!!
