The good news is that Nvidia Shield TV supports hardware decoding on the Shield for the following compression formats: When we try to play a video on Nvidia Shiled TV via Plex, Plex will try to transcode that video to be compatible for Nvidia Shiled TV and it always transcodes video to H.264. Why Plex spin when using on Nvidia Shield TV to play MP4? Has anyone else experienced similar problems? I am looking for a fix that doesn’t involve converting all my MP4 files to MKV. Everything is updated to the most current versions. I have already tried factory resting the shield, re installing plex, and the plex server and this did not fix the problem. When I use the shield server I can play the same file just fine on my computer, roku, and X-box which makes me think the server is working fine and its something local with the shield keeping me from playing those files. When I select any MP4 file to play on the shield using the shield as a server the spinning logo just spins forever and it will never play. I am playing MP4 files on the NVIDIA Shield.
