When we moved into this house a couple of months ago, we signed up for Sky+ (we had regular Sky previously). My in-laws, as a housewarming gift, have ordered us new living room furniture, which will necessitate the room being re-arranged and the TV moved, but the cable isn't long enough. We had an extending cable for the regular Sky, but the Sky+ splits in two where it hooks up to the box. Is there something we can get to extend it ourselves, or do I have to have Sky come out to do it?
