I am not able to do so, yet... My Sound system, and I are about 300 km apart the next one and a half week.
And I want to try this on my real sound system, not on some PC speaker system, or a system with some defective speakers.
The problem is, that I have no native HD-DVD Player... But I hope to get the French BD next week...

I've no intention of creating some kind of fusion between one of the lossless tracks and the lossy DTS from the JP DVD.  Doing so would be highly experimental, require perfect synchronization of the two tracks, and could well lead to errors that might come to light only later on.  Why bother just for the sake of having some technically lossless sections when the alternative is a full-bitrate DTS track that should be pretty transparent to the source, looks to have good fidelity, and requires no alterations to content apart from perhaps swapping in the LFE from another source?

Given what's been posted above about the LFE in DTS tracks, I think that the best thing to do is output FLAC 5.1, which people can either mux to MKV or convert to PCM if they want to author a BD and burn it to disc.  That should cover all the bases.

By the way, would someone with the 2015 BD please demux it with eac3to and post the log?  I'd like to check something.

You can, but I have a simpler method.

Just use mkvmerge to mux it in an mka and extract it from the BD in one simple move.

An mka also makes for easier delaying.

MakeMKV is good and it's free whilst it's in it's beta testing (which seems like forever).

It doesn't rip bluray, but it does remux it.
If you only want the audio file, it's perfect for the job, a very light and simple program.
If you want the video as well, Handbrake might be even better.

MakeMKV rips too. Just use the "Backup" function and it creates a decrypted 1:1 copy of the Blu Ray.

So, any more possible BD/DVD/HD-DVD releases that we should check?
UK HD-DVD is stated to have French audio, so it is assumable, that it is the same, as the French disc.
Some other places, we could dig our ears into?
Maybe some other regions were as lazy, as Studio Canal regarding cutting the new mix down to TV Version...

Thanks, but no need for me, I expect the BluRay to arrive next week...

Here's a spectrogram of Stamper's track.



It looks like the HD DVD.

EDIT: I added the spectrogram to the comparison in post#150.

So, the Jap full bitrate dts is still the best choice, you'd say, Chewie? Are you motivated to work on a resync to both the old master (Japanese Blu-ray/Team Blu, Skynet, 2015) and the remaster (2D and 3D). They would be essentially the same, except for a starting delay for each and an additional 4-frame delay in one more spot for the remaster.
