I'm in the process of setting this up. I need to make a new template for my receiver but found a quick fix in the mean time.
I'm using the Onkyo TX-SR304 template and all that was required is to select the A/V Properties and learn codes for 'skip back' and 'skip fwd'. Then your channels should work.
I've also been playing around trying to build a new template in HADesigner and if I can get my head around all that I want to start seeing what I can come up with including looking at the radio controls.
If you want setup HADesigner and go through Thoms videos which are great and help get up to speed pretty quickly on the system. Then you can alter and improve that screen
