Well, according to what is available on the Spleen, the GOUT synced BD’s of SSE and ESB Grindhouse have all the English tracks you’d expect from the Despecialized edition (plus Portuguese as desired by the uploader), including the DTS-HD MA tracks. Maybe what we should instead be asking is: dear God, HOW did you author these BDs? Also, how many audio and subtitle tracks can this method handle, assuming it has a menu (which it should, if it has selectable crawls)?
It’s very easy to make BDs from MKVs that have compliant streams. That’s what we always do, and that’s why we make the MKVs compatible. Basic menu-less BDs made with tsmuxer can have tons of audio and subtitle tracks. Many of us here have used tsmuxer to make our Star Wars BDs with DTS-HD MA audio.
Seamless branching discs are another issue. Most commercial software seems not to be compatible with our DTS-HD MA tracks we use here (including Adobe Encore, etc). There is a workaround for that, where you can use filler audio tracks (pcm, ac3, whatever), to build your menu’ed disc. Then you can use multiavchd to replace the tracks with DTS-HD MA ones. But multiavchd doesn’t play nicely with seamless branching discs, from what I’ve seen. It just rebuilds entire separate streams for each playlist, I think.
In theory, commercial software like Encore should work with DTS-HD MA. There’s just something about our Star Wars tracks that makes it think they’re 3+ hours long and incompatible. It’s probably something that can be fixed, but I wouldn’t know how to do it.
