We have digged into this issue before and if I recall correctly there is no surround flag carried by the DTS 2.0 data stream that can be detected by software, unlike Dolby Digital 2.0 which can either be "stereo" or "surround" (or even 2-channel mono). So how we could be expected to enter this information correctly in the database would be anyone's guess. Since there really is no compelling reason to make the distinction anyway, I have suggested that the program option should simply be labeled as "stereo/surround" to avoid this sort of unecessary complication. Sometimes I think we demand too much technical minutiae for our own good.


I don't think that's 100% true. The DTS-HD Master and DTS-HD High Resolution formats have backwards compatible "Surround" Cores.

Audio specs do not have to be confirmed by software, if you can confirm if with a home theater set-up. Many home theater set-ups can decode DTS-HD Master Audio and downmix to Pro-Logic decoding whether that stream is "Surround" or not...just like any other 2-channel audio source.

You've never noticed that when playing a Blu-ray on your home theater?

I just know that it works, I have no idea how to reliably and verifiably tell if it's stereo or surround. Sometimes my ears can give me a hint but even stereo tracks can trigger "false" surround information in the rear channels depending on how much processing the receiver does with the signal. I can of course force it to play stereo, doing a downmix if needed, but that doesn't tell me what the source actually is. Maybe you would be so kind to describe how you confirm that a DTS HD Master 2.0 track is enconded in surround or stereo? (I know how to detect mono so that's not a problem).

My Onkyo receiver will decode it if set to Dolby Pro-Logic II. Sometimes it shows these as regular 2.0, and sometimes as Surround. I've always noticed that matching what is displayed on either the release back cover or the disc menu. If it shows Surround on the package/disc, that's usually what it decodes as. It won't differentiate between 2.0 Mono and Stereo/Surround though, but that's the same with other formats.

Interesting, so somehow the receiver can detect the difference between 2.0 surround and stereo automatically. I wonder how it does that, and if it is consistent across different models of receivers.

Want to bump this as I just got Nebraska which has 3.0 channels for all languages (and both DTS-HD MA and Dolby Digital). How should I enter these?

You can't. You can post a feature request but don't expect any answer from Invelos = Ken. He doesn't care. He already got your money.

I've just bought a Blu-ray with two DTS-HD Master Audio 3.0 tracks on it.

Just out of curiosity, which of the seven channels are being used?


I have seen both:

a) Left, Center, Right
b) Left, Right, Rear Center
