I knew that the Prequel Trilogy was originally shown in DTS-ES 6.1, even The Phantom Menace.
Now, what I found was that the DTS Cinema discs are oddly only in 5.1.
I think this may be a minor screw-up since I think the .wav filer are actually supposed to be encoded into DTS-HD Master Audio 5.1 ES Matrix which can be matrixed to 6.1.
The official Blu-rays are in discrete 6.1. And there are many Blu-rays with discrete DTS-HD Master Audio 6.1 like Harry Potter 1 and 2 Ultimate Edition, The Lord of the Rings Extended Edition Trilogy and the Japanese Blu-ray of Spirited Away.
I don’t know which Blu-rays are only DTS-HD Master Audio 5.1 ES Matrix (which can be matrixed to 6.1) but I do know that the Japanese Blu-ray of Howl’s Moving Castle had this, which was a contrast to the other Ghibli 6.1 Blu-rays (Spirited Away, Tales from Earthsea, Ponyo on the Cliff by the Sea) which were all discrete 6.1.
And if we decode the matrixed channel to a PCM file. Maybe we can recreate the DTS Cinema audio in discrete 6.1.
I know the only Star Wars movies in 6.1 are the prequels but we might as well do it for the Special Edition of the Original Trilogy as well.
I can’t actually do this since the conversion might be too much for my weak laptop and I don’t know where to get the files themselves, even in the Spleen, they are very rare.
If someone is going to do this and follow my idea. Then be my guest.
