I've owned the Denon 2700 for a number of years. Also attached I have a Milly 2.4.6 DTS decoder. The other day, I watched a movie in DTS (6 channel input) and had no problem. Trying to go back and play a DVD in Dolby I am getting nothing. The digital selection also no longer makes that 'click' noise it always made. I can get audio through digital using the 6 channel input (DTS pass through). Is it possible the Dolby Surround function is fried? All other audio capabilities are fine. Makes no sense. I am using a Toshiba 6200 with dig. coax directly into receiver. Digital optical is feeding the Milly (from the Toshiba). I have had no problems whatsoever with the unit. Am I doing something wrong? Any advice is appreciated. Thanks, michael c.
