Lately, it seems like Plex has more and more issues playing media on my nVidia Shield. Certain movies and tv that play fine on my phone (android), roku, Mi Box, and web browser will not play on my Shield. It's not all media, but it is always the same media. I haven't started to dig into it the commonality, but has anyone else seen this? If I install Kodi with the Plex plugin, the same videos will play just fine. I find it surprising I have so many issues given how closely the plex devs worked with nvidia to get the server working on the shield; I would expect playback to be a breeze.
Update: After using ExportTools to export all of the codec information about all of my media, I was able to narrow down playback issues to any media with EAC3 audio. With that information, I was able to identify a resolution which was to delete the Codecs folder in my plex application path on the plex server itself. Upon restart, all of my EAC3 media is now playing without issue! Thanks for all the suggestions from everyone.
