Sony STR-DH810 - Want to associate SAT/CATV button with HDMI-3 input
I have just bought a Sony STR-DH810 AV receiver. I have wired it up in a similar way to that shown in the operating instructions, with my Sky box connected to HDMI-3 (note that this is the *only* connection between the two boxes). When I select HDMI-3 as the input then I get audio and video working fine. However, I have been unable to program the device so that I can get this when I press the SAT/CATV button. I think I've managed to get video re-assigned, but have had no luck with the audio. I understand that I may get more features if I use an optical link, which I am prepared to explore as an option, but for now I'd just be happy to get the current signals appearing under the appropriate button on the remote.
I tried contacting Sony support, but all they did was explain how I could program the remote to control the Sky box, which is certainly something I'll want to do as a next step, once I've got trhe CATV button selecting Sky as the audio *and* video input.
Any help gratefully received.
