see the latest update it has a fix I believe for this…

you need to update your server as your client is already updated.

I haven’t tested but i believe this is a fix for what you are reporting.

If the subtitle is not in SRT or an other ‘text-based’ format, then Plex server has no other choice than to ‘burn’ it into the video picture. Which produces cpu load.
Because the TV cannot decode other subtitle formats.

I have the same here. Samsung MU7009 with 3.2.2 and PMS 1.10.1.4602 (also tried with beta 1.11.2)
file has SRT subtitle included (I also extracted the subtitle)
subtitle is SRT - 1000000%
doesnt work

to nokdim
I dont have plex pass,so i cant dl beta ver 1.11.2

to OttoKerner
subtitle is srt and i try all subtitle settings,
Problem still same~

to LucaToni82
U can try play movie with NB and enable subtitle
It work fine~

So Strange thing.
Nas do transcoding and burning subtitle even play movie with Samsung TV app or NB.
Why only use app makes nas cpu 99% usage and use nb play movie work fine ?

as i say,i install plex media server ver 1.10.1.4602 at begining
all movie can play smoothly with subtitile enable

but when i update samsung tv app to ver 3.2.2 —>autoupdate
enable subtitle makes NAS CPU 99% usage when play movie use Samsung TV app
I dontknow where have older ver app to downgrade .

Some sort of information: https://forums.plex.tv/discussion/307151/plex-for-samsung-2016-televisions#latest

Thanks for info but I already knew that.
As mentioned I have tried severall options with new/old Tizen App and PMS - in every case I cant play subtitle.

When I use the same file with same TV in combination with Twonky Server my TV plays with SRT subtitle without problems. So the proplem should not be my TV - there is something in combination with TV and PMS, maybe one click in options but I try everything and I dont know what else I can do.

Any news or solutions on this?

very awkward from PLEX team to bring out a client that needs transcoding to have SRT subtitles when XPLAY (made buy a 3rd party ) on my 2017 LG OLED TV with Synology NAS plays all 1080p and 4 K movies Flawlessly !!!
Plex TEAM we payed for LIFEtime pass to watch movies with subtitles !!! is this something too much to ask after 5+ years
