Nvidia Shield Plex video freezing only on "TRUEHD" audio movies if quality over 720P
I recently noticed that when I play some movies that the video freezes immediately upon playing the movie and all i get is the sound playing. The movies play fine from ios, android, web, and firetv. This is streaming from my server on a gigabit local LAN. I was able to get the movie to play by uninstalling all updates, clearing data, and clearing cache. I signed back in and it played. But the first time i paused the movie and started playing it again the video was frozen. When I fast forward the picture changes to a frame of the movie that i fast forwarded to and the sound starts playing. When this happened again i checked the the updates to plex had not yet been installed after the removal. I then installed the updates and tried again but no luck. In each of these tests i did restart the shield device.
Plex server is running version 188.8.131.5249
The movies are .264 mkv files.
Has anyone experienced this problem? What do I need to provide to help with the troubleshooting?
