On my Denon DVD3930, the function "Pure Direct Select" toggles between normal, mode 1, mode 2, all off. The function "HDMI Format" toggles between auto, 480/576i, 480/576p, 720p, 1080i, 1080p.
Does anyone know if/how I can get my hands on respective hex codes? Denon sent them to me for my AVR3805, for the commands 0.0db, -20dB and -40dB. I then sent the hex codes to Logitech Harmony support, and they added the IR codes into my account. I believe these 3 codes are now available for anyone w/ compatibile Denon AVRs (and a Harmony remote, of course).
I should be able to do the same thing again, but need the codes. Twice I called Denon tech support, got 2 different agents, and neither even knew how to find out if the codes existed.
