I've been having a little problem lately with my DHC 80.3. For some reason, with Dolby TrueHD ONLY, the audio drops out for a split second at a time, every few minutes! Like somehow is tapping the mute button on and off. It happens very often to throughout a movie. It only happens with Dolby TrueHD, however. I tried playing with the HDMI cables with no luck. Anybody have this problem or know what could be causing it?
