Hi,
I am running the latest PMS on Windows 10 on a Core i7 4790 and watch on a Samsung 2017 Smart TV
When I watch a movie with DTS audio (AC3 is no issue) every few minutes the video freezes for a split second (probably 0,5 to 1,5 seconds) but the audio plays fine during this time.
I restarted PMS to get fresh log files and watched a little bit Avengers Endgame. Around the 19:54:50 mark (+/- 10 seconds) there should be a big “freeze”, I hope you can see something in the logs.
I’m having the exact same issue…
Running PMS from my Windows 10 system and viewing it on my Samsung TV with the Samsung Plex App.
Freezes occur quite frequently and audio keeps playing while screen freezes for like 3-7 seconds. The issues started a couple of months ago.
I have the same issue as well, please fix this as was great until a couple of months ago.
same issue on my system as well, synology ds 918+ with a samsung tv - only have the issue when the file has DTS sound - DD is OK
Same issue here. Picked up the Samsung 70" UHD during the Best Buy pre-Black Friday deal. Plex for Samsung 4.5.1 (latest available). Maybe 1/2 a dozen times during a movie, video will freeze for 2-3 seconds while audio plays fine, then video will “catch up” and continue.
It was mentioned in another thread to disable Direct Stream, basically forcing it to transcode even when unnecessary. This did not work for me; issue persisted whether both Direct Stream was checked or unchecked, or whether Direct Play was checked or unchecked.
I Think this may be linked to this:

I don’t now how this topic could be related here.
Completely different problem
yeah that is not the problem here - if it was, there would be a problem with all files, not just the ones with DTS Sound
im pretty new to plex (maybe 6 months) - is there something we can do? open a ticket or something?
I have the same problem. The pictures freeze 1-2sec,but the audio still run. I tried 3 Samsung tv with Tizen, and for 1-2 months ago got this problem. I tried reinstall, but doesn’t work. This is only happening when i use transcoding, direct play is fine.
Can someone confirm the specific workaround for this? Ive gone into settings, and tried direct play and direct stream checked, both unchecked, and each checked individually. Still frequent pausing. Are there other settings that need to be set?
The only “workaround” I know is to allow DTS in the PLEX app (only a possibility up to 2017 Samsung TVs).
Then video runs smoothly but you also have to change settings in your TV every time unless you want to be stuck with Stereo.
I am experiencing the same issue with a Samsung TV (Tizen 4.0, Plex 4.5.1). I also run Plex on an Apple TV, Vizio TV, and even a PS4 connected to the Samsung all without issue. The video only freezes when using the Plex app on the Samsung TV with DTS audio. I saw in other posts that a Plex version 4.11.x is available. Does this fix the video freeze?
Use ffmeg to recode audio only to ac3 fixes it, if the Blu-ray rips that don’t have a ac3 track already.
c:\ffmpeg\bin\ffmpeg.exe -i z:\xxxxxxxx.mkv -map 0 -vcodec copy -scodec copy -acodec ac3 -b:a 640k z:\xxxxxxxxxxAC3.mkv
this is what i use, replace drive letter and xxx with source and destination.
Well converting our audio tracks of course fixes the problem but I hope you are not serious that this is a solution for the bug in the PLEX app 
Well for me that bug has been there since I started using Plex, and its still there, so I take things into my own hands. If your prepared to wait, then its not a solution.
Was really hoping an update would resolve this issue but as of tonight, testing on Plex 4.15.2, I can confirm issue persists.
It´s just odd. The Plex app gets the same video stream with “direct stream” in addition to a converted DTS audio stream or a native AC3 audio stream.
But with the former the video occasional freezes.
Maybe a developer sees this thread and can investigate.
Might be out of the woods on this issue, but looking to others to confirm. As of Plex for Samsung app version 4.19.2, I watched 2 full length movies with DTS audio track and did not see a single stutter or delay.
