Help with stuttering
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.
can anyone suggest what the problem may be? Thanks
