Hi there, I have an xtrend7500 and it outputs via hdmi to the main tv but i also use the phono outs to connect to an rf modulator to connect a coax feed to the tv in the kitchen. now the picture thru hdmi is as fine showing full picture but for some reason thru the phono outs, on the screen in the kitchen connected by coax it outputs the epg screen with the picture box in the top right corner shoeing the channel which on the main tv is full picture. If anyone can help me it would be appreciated
