Hi Forgive my ignorance but i'm having a nightmare changing inputs via the supplied denon remote control for my new AVR-2805. I have a phillips pronto and need to learn the command for changing the amps input to TV, DVD etc. Now I would've thought just pressing TV (or any other input CD, DVD etc) on the remote would change the input over, but it does not. The instructions don't seem to help at all either. I've tried pressing the AMP button first (as this seemed to help on previous receivers i've owned) but it makes no difference. Anyone able to help me???
