Hi all. I'm a dm800 user for a long time and never had any problems. I'm really satisfied with my receiver. But, for a few days I've one problem that worries me a lot. There are some tv channels that has no sound, In the audio info says that the codec is Dolby Digital + but there're no sound. It's funny because if I see a HD channel with AC3 normal codec and inmediatly after zapping to DD+ channel and deactivate downmix..... eureka! I hear the sound. Do you know why? There is a solution for this? thanx and regards.
