I have made a number of attempts to program my Genie's RC-71 remote to control my Sony STR-V333ES Stereo Receiver. The receiver is listed in the selections, but when I select it, nothing happens and I get a message, "There was an issue with programming your Sony Audio with your remote. You can try again or set it up later." I expected the light to flash on the remote when it transmitted to the receiver, but there is none. Do I have to set the remote to IR first? I thought the RC-71 could transmit in IR and RF at the same time.
