I have a 4K file that stutters like crazy - the video essentially drags behind while the audio plays normally, rendering it unwatchable. MediaInfo reports the following about the file:

A couple of notes:
- Infuse for Apple TV is able to play back the file without issue
- dropping back to the old video player in settings allows the file to play smoothly but at the expense of Dolby Vision
Any advice would be welcome!
