5.1 Dolby Vs Dts
DTS:X will only work if the content is in encoded in that format, if not it will use 7.1 or 5.1 surround sound and give you virtual 7.1 / 5.1 surround sound as an output, not upmixed virtual DTS:X like with Dolby Atmos for Headphones. DTS takes up more space that could be given to improving the video quality, and without superior audio equipment it can't be said to sound any better. Even with so-called 'superior audio equipment' I don't think anyone could ever tell the difference between dts 5.1 and Dolby 5.1.

Does it disengage my settings from MCACC? That is what it is supposed to do because uncompressed means that the digital samples are sent as is in 'PCM.' It should not disengage anything other than dialog normalization. Originally Posted by Carpaccio One more question about another movie: The Prestige.

Dolby Dts Vs Dolby 5.1
It isn't a 'bad' choice, and in some cases is the original mix for the given movie (if the movie is older than 1993, it was not originally mixed in 5.1); which may or may not be of interest to you. Dolby Digital (or AC-3) is a 5.1 or 6.1 (if it's 6.1 it will say EX) scheme, it's lossy but you get discrete surround sound. If you're going to watch the movie in stereo, I would suggest the Dolby Surround mix, otherwise go with AC-3. Background: Regarding the 5.1 MPCM option, this is likely going to be closer to the audio you would get with a Blu-ray or HD-DVD, in that it will be lossless (branded lossless formats include Dolby TrueHD and dts HD Master Audio). If the receiver can handle 5.1 MPCM (which requires an HDMI connection, or an external decoder and 6-channel analog connection), it's likely to be a technically superior track. However, Dolby Digital and DTS 5.1 (sometimes referred to as 'legacy codecs' or 'lossy codecs') are generally considered to be 'good enough' and differences with TrueHD/HD-MA are generally very small (if not non-existant), all things considered. Regarding whether or not you lose MCACC or other features, it depends on the receiver - refer to your owner's manual.

It should not mean a loss of EQ and management, but I vaguely remember some of the earliest HDMI audio receivers dropping bass management and/or other features when handed a 5.1 PCM signal. This should be of no consequence with a new-ish receiver though.

Dts 5.1 Vs Dolby 5.1
Not 100% on the cables. It is better tho. EDIT: just seen that you are getting PCM so seems to be working for you. Don't know what your set up is. Might be totaly wrong on the 5.1 on the toslink cables maybe thats something elce i was thinking about. I'm using HDMI from the BD player to the receiver as well as from the receiver to the TV.
