I have just bought the above amp and am basically happy wit the sound but i have a couple of issues which i hope someone can shed some light on. First i cannot get the video monitor output from the s-video connector to work ? the composite works fine and i have checked both the cable and the tv and they are fine too ? Also i cannot get the coaxial dig in from my dvd player to show up anything either but once again using composite it is fine ? am i missing something ?
