Hi,

The playback engine is quite different between a full BD structure, and single m2ts or mkv files.

Considering in particular that a BD license is needed to decode DTS-HDMA, does the Dune Prime 3.0 decode fully this format when playing a single m2ts or mkv file? Same question for Dolby True HD.

The question also applies for Lite playback of course. I read somewhere that full audio decode won't be available for the smaller Dune models which only support Lite, hence my question for other models.

Thanks for any clarification on that matter.

IF the video file is encoded with the HD audio format then when replayed the Prime does decode or passthrough (depending on the Prime setup) that audio to your AV system. However it is possible that the rip to MKV etc may have removed the HD audio and therefore you may only have the AC3/DTS soundtrack in the file, so it obviously can't then be set to the AV system.

I have used a TV101 (BD-Lite only) and know that it does indeed decode or passthrough the HD audio - although there seems to now be a bug in the latest firmware that looks like it has broken the HD audio, but as I no longer have a TV101 to test it on I don't know exactly what is going on.

Yes, of course, my question was about MKV files that include the full DTS-HDMA stream.

The Dune does decode, that's for sure, but do you know as a fact that it decodes fully in that case?

It could be only decoding the core rather than the full loseless stream,due to the fact that it's not using the actual BD engine software.

I would really appreciate a definitive answer by somebody who works with Dune.

Why don't you just rip one of your BDs to a single file and test it yourself?

The difference between DTS-HD 1.5Mbs and DTS-HDMA is often slim, depending on how good is the source.

I would like an objective answer, not a subjective one.

If the AVR registers the audio source as DTS-MA and TrueHD is that objective and definitive?

I just ripped one chapter of the Green Lantern BD to mkv, keeping both the DTS and DTS-HD MA tracks, using the latest nightly of Handbrake. DTS was enabled by default, since I put it first in the audio chain, and when I switched to DTS-HD MA, my Onkyo TX-NR809 showed DTS-HD MSTR, just like it should.

So, that should answer your question.

Thanks for taking the time to do that, but no, it does not.

I'm not speaking of pass-through, but about decoding.

Whether the Dune decodes the full stream or only the core, it will output PCM, and there is no way for the processor to know what was the source of the PCM flux.

A processor will never show DTS-HDMA or Dolby True HD when the Dune decodes, it will only show PCM. It will show the same thing for AC3 and DTS.

Since your processor shows DTS-HD MSTR, this means that you set the Dune to audio pass-through.

My question is about what happens when it's set to decode to PCM.

Please see my answer above.

Now I see what you are asking. My AVR accepts multichannel PCM. If the audio track has 5 channels, it only plays in those channels. If the audio track has 7 channels for DTS-MA, and all 7 speakers are active (only 5 are active for DTS), will this confirm the decoding of MA correctly?
