Android TV stutters only at x1.0 Speed

[Chase Spencer]

Version: 10.8.13
Installation Method: Windows Installer (Server) and Google Play Store on a 2023 Onn Android TV and a Fire TV (Client)
Issue: 
When I play about half of my library, on my android TV (at 1.0 speed), the framerate is incredibly low, there is some stuttering, and there are audio issues.
Additional Context:

• The shows all run fine on my windows PC, iPhone, and iPad.
  
• Weirdly, they also run as expected on the android TV on either 0.75 or 1.25 speed or when I use an external player that can disable hardware decoding.
  
• On all three devices, the video is direct playing, so there is no transcoding going on (I think this means no logs).
  
• Unfortunately, setting a streaming mbps limit on my android TV did not fix the problem, the stuttering just continued at a lower, transcoded resolution.
  
• The videos shouldn't be difficult to process: it's happening with 1080p and 720p h264 videos.
  

Have others experienced android TV issues like this? I don't know what to do from here. Thanks!
