My Sister-In-Law has just purchased a LG RZ37LZ55 TV. Basically, she likes to watch either freeview or other channels via satellite, which means switching inputs. The only trouble is that it's quite a slow & laborious task of scrolling through the relevant inputs. My question is this, is there a way to conveniently setup the TV where you can access the correct inputs without scrolling all the various inputs? Thanks, T.
