The SR control is only if you have something like a Pioneer reciever or other pioneer products that support SR+. My Pioneer VSX-D814 has that control in/ control out too. The remote has a setting to turn on the SR+. You have to buy a special cable for it though, they say a three ringed 1/8" jack. But its to control the TV with one Remote and not change the the input setting on the remote/ reciever
What you should choose does not end in the here and now, but how much you want to deal with it in the futre
