Try switching to the Linuxserver container from binhex

You're going to need to force a transcode by changing the bitrate of the active stream if you want it to transcode. Right now it appears that it's direct playing which will not use the iGPU (or CPU).
 
 

When I posted about this type of issue, I was told to just monitor if more occurred. So far I've only had one on my system.

Files being "Unprotected" means you do not have a Raid1 or Mirror cache configuration(parity for cache basically).
 
First you can use mover to try and move the files back to the Appdata share on the cache but if there are any duplicate files, mover won't move them because it will not override files of the same name.
 
To do this, under the Appdata share settings, assign the primary storage to your cache pool, set the secondary storage to the array, set the mover option "Array --> Cache." Stop the entire docker service from the settings menu and run mover. Once you're done, set the secondary storage option back to "None"
 

 
If you have files left over you need to decide how you want to proceed further.
 
 

Yes sonarr and radarr have an import function. It will rename and move the files when they’ve finished downloading. You shouldn’t have to do anything manually.
 
the *arrs apps also have batch renaming for already imported files.
