I am a new Directv customer and have ordered the Whole House Video system with 2 HDVRs and 2 HD receivers, but failed to order up the internet connection kit. Should I roll the dice, let the installer show up and if he does not have the install kit canx the install then or just canx now and reschedule for a later date after getting the install kit added to my order? Not sure if it matters but I live in Huntsville, Al.
