I have connected sony bravia tv to sky hd via HDMI 1 and panasonic home cinema surround sound to tv via HDMI 2. With an optical cable from sky box to home cinema. The sky remote turns on the tv and home cinema but the panasonic defaults to home page and therefore optical out has to be selected via panosonic remote and the HDMI 1 needs to be selected with sony remote. Is it possible to configure set up so that it turns on using only the sky remote ?
