I bought this and after great support from Keane in the UK - thanks Mark, I got it up and running. Watched Layer cake - no problem. Switched to John Woos bullet in the head - no sound, nothing, no matter what I teaked. Put in Minority Report - sound again!!!!! Anybody got any ideas? Also amp needs to be substantially turned up when it automatically switches from SAT BOX to DVD. Anybody shed any light on this too please? I am using optical leads in and out for all devices. Thanks.
