Screenshots: Pr export settings: tsMuxer setup. I changed the file names after export from Pr from OpenHouse to M4V10-15: Toast setup: Toast encoding settings:

I think it’s the latter. I’ll post some screenshots as soon as I can.

Sorry you had to do that. You may not have to give up on the software just yet. I uninstalled with CleanMyMac X and reinstalled a freshly downloaded version. I exported from Pr as H.264 Blu-ray with bit rate set to 10 Mpbs and 15 Mbps max. I muxed the video and audio from Pr in tsMuxer as a .m2ts file and used that as the source in Toast. I set Toast to it's default settings except I changed the encoding bit rate to 10/15 max to match my Pr export and I set re-encode to Never. I had a successful burn to disc image with no re-encoding by Toast. I'm going to try a 20 Mbps/25 Mbps max export and burn now.

Steps to reproduce: Export a ProRes 422 MOV file from Premiere Pro 2020 that is 1920x1080 @ 29.97 fps, Upper Field First, square pixels. Ensure Toast Video Prefs set to NTSC. Set Toast 19 Pro to burn a Blu-ray Disc image. Import the ProRes MOV file from Pr. In either Updated or Classic mode, prepare menus and encoder settings for burning a Blu-ray in Toast. In either Updated or Classic mode, burn the BD image. Result: The video in the disc image is PAL 25 fps, not NTSC 29.97 fps.

I've just run into this problem myself. Toast 19 Pro refuses to import elementary m4v and wav files from Pr that are BD-legal. If I export a muxed H264 mp4 file from Pr, Toast imports it just fine. But then it insists on re-encoding it no matter the settings in Toast. I have to see if the audio is the problem; maybe AAC audio in the mp4 file will work better.
