BDMV file keeps studdering/loading

Hello, recently downloaded a blu ray file (46gb) and have noticed that it’s studdering alot, I’ve had this happen before with other movies and the solution was to go through the add file section, click on the movie and not skip anything so that the movie would load through out watching it, but this is a bdmv file so it’s complied of many different types of parts and clips, so that’s not an option. Anything I can do ? I’m on iPhone 13 pro max through the app.

What settings do I change to help
with studder/ constant loading
