I've recently bought an LG 43UJ701V smart TV with WebOS, however I'm experiencing playback issues with Plex. I have confirmed that both the Plex app and TV software versions are up to date.
The issue i'm experiencing is constant buffering of the video, it's not being transcoded to a different format but is using the "DirectStream" method. I'm unable to see any major load on the Plex server so this does not look like an issue with the server, I have also checked the network and used ethernet to test and this does not improve the issue.
When checking the Plex status in the browser I see that both the audio and video are as "DirectStream" but the status is as "converting (throttled)".
Any help with the issue is greatly appreciated and if you would like me to provide further details just let me know what you'd like and I'd be more than happy to provide!
