Just upgraded my clients to R22's. I have my sound set up to a Denon receiver. Must I have my audio set to Dolby Digital on my R22's? The Directv tech that installed all my DVR's, set them all to Dolby Digital "OFF". I have my Denon set to Dolby Digital. I just call D*, she said to turn Doly off on my receiver...I started to ask why when we were disconnected. Any help? My Denon is an "AVR-X2000.
