I used the Minnetonka for years, both RTAS and VST. Worked great but would definitely need a test run to see if it works with Catalina.
I believe LtRt found on film optical track are only PL-1, for 5.1, it uses Dolby Digital (also known as AC3), and are printed between perforations. Pretty sure the PL-2 was strictly a consumer format.

I will most likely use a SDU4 strap on the output of my Resolve rig. Thanks.

I still make LtRt's just because it makes so easy to mix. I monitor and mix in 5.1 but the encoder automatically creates a balanced stereo version of it for you.

Yeah it was called Dolby Surround. Are you sure all the films being scanned are LtRt mixes? I work with a lot of archive material from the 50s through to the 90s, and it's mostly mono with a bit of stereo in the 90s, albeit this was animation either shown in cinemas (the earlier stuff) or at festivals or on TV.
