I recently had an entertainment cetner built to house a new Samsung 50" DLP (that many readers and posters on this forum helped me choose). Can you hook up Tivo with a cable connection or do you also need a phone jack as I have been told? My cable jack is neatly placed in the back of the cabinet but the phone jack is on an adjacent wall - if a phone jack is necessary is it worth having an electrician put another phone jack behind the wall unit?
