My Myth box is the only thing connected to the TV so that's the only input signal (via the non-rgb scart socket currently, but via rgb scart asap). However, when I switch on the TV it defaults to a TV channel rather than the scart. Then I have to hit the AV button to cycle to the myth input. I want to just power-on and have the TV switch over automatically as it does with other devices I've used in the past. I guess these used Pin 8 or similar. One other thought is that (although it's another link in chain) is to use a scart switch box and have Myth as the default input to that such that the switch box has Pin 8 already wired. It's a lot of effort for such a feature mind!
