Everything's FINALLY installed. Question about the remote though. It's an RC65RX. I want it to turn my Tv (LG) on and off, and it's doing that. However, I want the volume control and the mute button to control my A/V Receiver (Onkyo TX-NR5007). How do I get it to do this? I mean, I can program it for the Onkyo, but the volume continues to control the Tv.
