I have a new Sony XBR-65A8Fthat is operating from both WiFi and Cox Cable.I also have a DVD player that is plugged into the Cox receiver (this is the same configuration I had with my old 46 inch Sony Bravia). My TV is working fine but I do not get any sound or picture when I try to use the DVD player. The old 46 inch required that the remote be programmed to recognize the DVD player. No instructions were provided with the new TV and its remote. How do I arrange the marriage of these units? The DVD is a Panasonic DVD F65
