What's the full codec and format breakdown of an example problematic file?
Is it something barely supported like 10bit H264? Or perhaps an ass subtitle incompatibility?
Could also just be as simple as bad wifi to the roku.

Original source medium : Blu-rayIt's the DTSXLL audio track, I guarantee it, there are people having issues on other apps like emby with high bitrate 8ch DTS on some devices.
If you force the second 5.1 audio track to be the default does it still have issues?
I'll reach out and ask them to try swapping audio.
The issue's on the Roku side, correct? Or am I going crazy? I've checked everywhere a long the stack and don't see bottlenecks.
I have 4 Roku's When they're great, they're the greatest. Stuff like this on large content is sadly not uncommon. They fix it in an update, break it in another. For single titles, i'll just run optimize on it.
It still runs better than the plex client on my smart TV's, but that's not saying much.
Do you have a similar file to compare it to? Because the only thing I could think of is network bottleneck
I was recently having issues with my Roku Premier stuttering on some media. It's hardwired to the same network as the server.
What fixed it for me was changing the audio output in the main Roku settings to stereo. This Roku use to be setup with a receiver to decode the audio stream but is currently sending audio directly to the TV. I think decoding the audio was too much for the Roku.
