Additionally I ask if we have the Theatrical DTS track for attack of the clones because if so, the previous paragraph will be irrelevant aas I can just mux that into the video file and I won’t need to export anything new from premiere.

Unfortunately as far as I’m aware we don’t.

How Attack of the Clones is the only film to not have an actual theatrical copy that isn’t a crappy bootleg in 2019 astounds me. Even the aforementioned DTS track would be something.

After you get the 5.1 sorted I’d love to give it a watch though, not many theatrical preservations of AOTC have been attempted.
