I just installed a Samsung BD-P1500 Blu-ray player into my modest home theatre. I have 5.1-channel audio using an old Sony STR-DE635 receiver. It processes 5.1 digital audio from my cable box (via coaxial cable) and it used to do the same for the DVD player (via optical cable), too, until it got replaced by the blu-ray. I was perfectly happy with the quality of the audio.
The blu-ray player is now connected to the receiver via the optical cable.
In the audio set up menu for the blu-ray player there are three options: PCM, Bitstream (Re-encode), and Bitstream (Audiophile). I chose the Bitstream (Audiophile) by trial-and-error, as it was the only one that sent audio through to the receiver in "Dolby Digital [3/2]". In other words, it gives me the same 5.1 audio that I used to get from the old DVD player. And I'm still very happy with the quality of the audio.
The PCM choice gives me only 2.1, and the Bitstream (Re-encode) gives me nothing.
These three options are described in more detal on pages 35-36 of the owner's manual, which can be found here:[Link: samsung.com]
The Bitstream (Re-encode) is recommended for a receiver with optical input that can decode DTS. The problem, of course, is that my receiver can't decode DTS.
So, what's my problem? Maybe you've guessed it? It occurs only when I play a blu-ray disk with the DTS-HD audio (see, for example, http://www.foxbd.com/
I get no audio coming through for the two bitstream options, and get just 2.1 audio using the PCM option.
I know that I should upgrade the receiver, but I'm having trouble figuring out what upgrade to make. (An alternative would be to replace the BD-P1500 with the BD-P2500 and use the 7.1 analog outputs).
One question I have is the following: If I replace the receiver with a Sony STR-DG520 I should be able to use the Bitstream (Re-code) option as it has an optical input and can decode DTS. Will this option also allow me to hear the DTS-HD audio in all of the 5.1 channels?
Another option would be to upgrade the receiver to a HDMI receiver that has DTS-HD decoding capability.
The main factor in making the decision will be cost versus value. But the question I need answered is will I be able to hear all 5.1 channels on the DTS-HD blu-ray discs using the optical cable connected to the Sony STR-DG520?
