I do have the AVR Denon X-2000. Can any of our members clarify a thing about the audio format. Suppose I play a Blu-ray/DVD movie which has multiple audio formats such as DTS, DTS-MA, Dolby Digital, Dolby True-HD, Stereo.The Denon supports all the above formats. Which format would the AVR select by default for play? Will it select the best format or it chooses randomly. Because sometimes I found despite the movie was encoded in Dolby digital, still the AVR preferred to select the 'Stereo' mode.
