Hi guys, think I may just be being particularly thick but I can't get my 785 to do what I want with my TV (details in sig). How do I get it to eg when I press "Play DVD" turn the tv to the correct input? For me that involves calling up a menu, scrolling down 4 to inputs, scrolling down the inputs and pressing 'enter'. How do I tell my remote to do that? Am sure it's easy but it's defeating me currently... Thanks folks.
