Hi, hopefully this will be an easy fix... have recently moved and have had sky for the last couple of days. The problem is, the sound seems ever so slightly out of sync with the picture... i'm not talking huge amounts but noticeable and now I have noticed this all I find myself watching are peoples lips and getting annoyed when I see its out of sync! I've tried the audio adjustment on the Sky box but doesn't seem to make much difference... how would I go about rescanning the box and would it make much difference? If it makes any difference it is connecting to the 1912 via HDMI and Optical and then HDMI from the Denon into the TV. Thanks!
