Okay, so the Turbine audio is basically a lossless copy of the 25th Anniversary DVD audio mastering, with the limited dynamics in it. Fades out slightly earlier and there’s a beep at the end.
But it does mux straight in with the 4K video from the UHD blu ray, no offset needed (well, with my UK copy at least)
So great to finally have the original mix with the original theatrical cut again, in wonderful quality. Thanks so much BenjaminG!
