I have a Denon AVC-A1SE and an Arcam FMJ-DV27.I connect these together by coaxial. I can be watching a dvd movie when at any random time,the Dolby Digital sound will cut out.If i immediately select any of the sound options on the Denon remote then it comes back on.While all this is happening i can still constantly hear the sound through my tv speakers(if i turn the volume up on the tv).The DV27 is connected to my tv by RGB scart. I do not think it is a problem with the discs as i can go back an hear the Dolby Digital soundtrack at the same point it cut off another time. I am wondering if the Denon is playing up or not connected correctly as this has only happened since i set it up again after testing the Arcam AV8/P7 combo. I am at a loss as to what the problem is.
