Help with stuttering when direct palying

I’ve been using Plex for a while with everything generally going well. recently I’ve had a few files stuttering and i cant work out why. The film stutters at the exact same spot every time, and usually recovers and carries on afterwards. I tried the film in Emby and it did the same thing at the same spot. If i watch the film through the TVs built in DLNA player it plays fine. I’ve monitored the server during the stuttering and the file is direct playing, with the CPU and network usage hovering around 10-15% on the server.

Ive got an Intel NUC i3 as the Plex server and my main client is a Samsung KS7000 built in app. I mainly watch remuxes both HD and UHD which has been fine as long as they direct play, I know my server is not powerful enough to transcode so i always make sure the files can direct play. This issue where the file is direct playing but still stuttering has affected 4-5 different UHD files recently, after not affecting any of the first 40 or so UHD files. Any problems in the past have either been audio or subtitle related, but i am certain that these are not the problem in this case.

Ive attached the logs - can anyone suggest what the problem may be? Thanks

Sorry I can’t help… but I have the similar NUC i3 and it was working fine until recently. I checked and was told that if I can do less transcoding it will work better so I tried another file format and it was better but still problems I didn’t have before.

I avoid playing anything that requires transcoding, even just transcoding just the audio can cause stuttering i.e Dolby True HD -> DD5.1. That was the problem causing my issue, even though it was apparently direct playing the DTS sound tracks, by manually converting them to DD5.1 and stripping out all other audio tracks it solved the problems.
