Thanks jb66, but why can't Virgin simply 'splice' the input aerial cable at its point of entry into the room? One side of the splice would go to the set-top box in the normal way, and the other would connect to the in-cavity cable that I have which terminates at the other side of the room. I'm sure I'll need another set-top box at that point to decode the signal, but I don't understand why you think that Virgin won't touch it.
