At my work, we demoed a brand new Denon DVD-1800BD blu ray player which is now hooked up to the onkyo tx-nr905. The screen on the onkyo displays "DTS-HD MSTR" which from what I understand is DTS-HD Master Audio.
I just wanted to know what were the differences between DTS-HD, DTS-HD Master Audio and Dolby Digital Plus? Also, why wasnt DTS-HD Master Audio displayed on the onkyo when I had the sony bdp-s350?
