[Released] Terminator 2 CDS mix

[Swift S. Lawliet]

It's possible for 6.1 matrixed tracks to be muxed as plain 5.1 tracks but have the original 6.1 mix decoded back using Dolby Surround or DTS Neo:6.
One of the most popular cases of this is with Die Another Day.
The DVDs were both 6.1 matrix (the only Bond movie to be so and the only Bond movie to have a mix higher than 5.1 until 2015's Spectre) but the Blu-ray was just 5.1.
What is interesting, however, is that they are the exact same mixes.
It's apparently the same case with the first Terminator movie, which was just muxed as 5.1 for the all the Blu-rays when it's the same 6.1 matrix track on the DVD.
They're both MGM releases but this has also happened with some Disney films as well.

Unless I'm completely missing your point, yeah, that's just because the matrix encoding thing is not to do with digital codec encoding/decoding but to do with processing of the actual audio samples and placing them into channels. Lots of Blu-ray Discs (and LaserDiscs) have 2-channel linear PCM tracks that are obviously not explicitly encoded as 2.0 matrixed ("Dolby Surround") in any way but do indeed contain 4:2 matrixed audio, so the correct way to decode them would be using a Dolby Surround / DTS upmixing/decoding mode. You can take those 2 PCM channels and encode them to something like DTS-HD Master Audio as Lt+Rt (effectively instructing the encoder that they're matrix encoded) and this will signal explicitly to the decoder during playback that it's matrixed. So it follows then that it is indeed possible to encode a digital 5.1 DTS-HD MA / Dolby TrueHD track where the surrounds are actually matrixed channels (in the sense that the analogue audio samples they contain were matrix encoded), meaning that the proper way to decode them during playback is as 6.1 matrixed. It doesn't necessarily surprise me to hear that some "5.1" tracks are actually incorrectly encoded 6.1 matrixed tracks, given how many other issues are so often seen on modern releases.

Exactly!

Little titbit of info.

The recently released kaleidoscope version of the 4K restored Terminator 2 contains a DTS-MA 2.0 track

Does anyone have a link for the original CDS 5.1 and/or DD 2.0 tracks that sync to the 2015 theatrical cut BD?

I usually watch movies with headphones so it would be cool to have the option and see which sounds better.

Thanks!

Does anyone know what 5.1 mix is on the Japanese bluray released in 2008?
