Love the picture on my new 42PV500, particularly Sky - its far better than I had hoped. However I'm finding the remote control annoying, specifically switching between inputs. Can anyone help with the following: 1) How do I get it to switch on automatically to an AV input. I dont have a terrestrial aerial but it automatically switches onto digital TV, and of course there is no signal. In the setup menu there is a "Auto power on" which I have set to AV, but it doesn't make any difference (not sure what this function is for anyway). 2) I route my DVD player via HDMI - its extremely annoying to have to press AV then cycle through to the PC/HDMI/? option then cycle through to HDMI - I want one button to do this. Is there any way you can program keys to perform specific functions?
