What I CAN tell you is this ..... DTS started in 1993 so any movie before that year will NOT have it. That said, it is not a guarantee that movies made after will as we found out with The Arrival which was Dolby/SDDS ONLY.
I can do a search DJ, and see what I can come up with. I'm glad that you'll be getting audio wanted for the RH2 and BIO projects.
Cheers!!!
