If you have a relatively new TV you should be able to use a single cable -- an HDMI cable, to be exact -- to connect your receiver to your television. If you have an HDMI port labeled ARC/eARC on the TV you can connect that to the main HDMI ARC output of the receiver. Doing so enables you to hear onboard Netflix from your TV when you set the receiver on the "TV" input, while also enabling video to be transmitted from your other AV sources. If you have an older TV without an ARC-compliant port you will need to connect both an HDMI cable and an optical cable to the back of your TV. However, if you have a CRT or rear-projection TV with composite or component inputs you'll need a $1,000-plus receiver like the Marantz SR6015 or Onkyo TX-RZ50. Many receivers no longer offer switching for these legacy connections.
