I do not own many dvd-audio discs, but I am having trouble getting my 2910 to recognize the "dvd-audio" layer of a few discs. Everything seems to be hooked up correctly (5.1 out cables from player etc.) and I do not have a problem listing to the various layers of any sacd. My copy of "On The Beach" seems to play back in dvd-audio, but I have copies of "Harvest" and "Sea Change" that will only playback the DD or DTS layer. I can't find a way to get the 2910 to recognize the dvd-a portion. What am I doing wrong? Thanks in advance.
