Obtained new XR11 sound remote from Comcast. It will not recognize my Yamaha RX A2010 receiver so I have to turn on the receiver using one remote, then the TV with the XR11. Went to the Comcast website and tried their suggestion, which failed. Called Comcast. They came out 90 minutes late and were baffled as to why it wouldn't pair. They left, telling me it cannot be done. The Universal MX900 remote has no difficulty at all. Why does Comcast put out cheap remotes while charging us substantial rates for service? Surely I'm not the only person in America with a Yamaha receiver incorporated into their surround sound system… If they truly cared about their customers, they'd solve the problem pronto.
