I just received a replaced HR22-100 and have a problem when watching a program with Dolby Digital sometime when I pause or FF past a commercial I lose audio. If I change channels to a none DD channel audio comes back and then the original DD channel works. FF again same problem. Also, if I don't change the channel but cycle my audio system then the audio appears. I had a HR20 for years this only happened the day after the HR22 was installed. Anyone have any thoughts?
