Questions about connecting a blu ray to a reciever

[guitarplyrstevo]

So at my job I've realized that a lot of the receivers are not performing as well as they could because of the way they are connected and because of the type of audio signal it is receiving. For example: When a, lets say an Onkyo 805, is connected to a blu ray player, one of the best listening modes would be "Dolby D" or "Neo:6" correct? Because all the other settings like "PLIIx Movie" and "Neo:6 Cin" would be taking two channels and processing the sound of the other channels right? And "Dolby D" and "Neo:6" would actually be played the way it was recorded. Correct me if I'm wrong, that is just what I've realized after playing with receivers.

Anyways, at my job we have all our recievers connected to a board that splits the 1 optical signal from the blu ray player into more than 10 sources so we can connect multiple receivers. Well why is it that none of the receivers can go into "Dolby D" and "Neo:6"? The only available listening modes are the basic "stereo" "mono movie" "Neo:6 Cin" Neo:6 Mus" PLIIx Movie" "PLIIx Music" etc. From playing around with my own Onkyo receiver at my house, the only time "Dolby D" and "Neo:6" are available is if you connect the receiver using either optical or digital coaxial. So I don't understand why none of the receivers are able to choose that listening mode.

I've been wondering about this for a while so any help would be appreciated. Thank you.

My understanding is that Neo:6 is like Dolby Pro-Logic II and IIx. So, Neo:6 is processing the sound of the other channels, too.

I'd say check the settings on the Blu-ray player at work. Make sure that it is outputting a signal over the optical digital audio output that can be decoded by the receivers as Dolby Digital or DTS. For a regular DVD player, you would need to set the output to "bitstream" in order to get Dolby Digital or DTS on the receiver. An output setting of "PCM" on a DVD player would just get you two-channel sound. I don't know if that's true for Blu-ray players. I'm not that up on Blu-ray players and the latest codecs, and I can't remember if Dolby TrueHD and DTS-HD can be sent over the optical cable or not.
