Hi all. Hoping you can help me. Having added a new Roku HD1000 to my setup I need to use a particular Audio source and a different Video source. I can do this easily enough on the amp front buttons by choosing the Audio source (in my case VDP) and then pressing the Video Source button (bottom left) and choosing the correct video source. However, I cannot find a corresponding button on the remote for Video Source. I need this to build it in to my Pronto macro to make it all automatic. Does anyone know how do this, if I am missing something or if a remote code exists for this. Thanks.
