I have the mkv file for the Korean movie Parasite. The English subtitles show up when I play the movie with VLC, but not with the Plex player on my TV. In my case, Plex is installed on a Netgear ReadNAS 524X (1.19.2.2737). I have subtitles set to be shown with foreign audio.
Any ideas on getting the subtitles to show up?
Would you mind sharing some more details?
Is this an internal or external subtitle? Is it generally visible in Plex and simply not being displayed when playing the movie ā or is Plex not seeing it at all?
English language?Thank you for the quick reply.
Regarding my question, I believe it is an internal subtitle. Plex reports the subtitles on the opening screen as āEnglish Forced (SRT)ā. There is no external file, only the mkv. VLC sees the subtitles and shows them. Plex shows nothing at the bottom of the screen.
What type of Plex client is it where the subtitles arenāt showing (platform, client version)?
Can you reproduce this issue in another Plex client (e.g. using Plex Web or Plex on a phone / desktop)?
Also, be sure your settings/flags are set properly.
Plex Media Server is installed on my Netgear ReadyNAS 524X (version 1.19.2.2737). I only watch Plex content on my Samsung TV.
What should I do to try and reproduce the issue on a different Plex client?
Hereās the screenshot of my subtitle settings:

Oops. Looks like I pasted the text only. Iāll try again. Hereās the screenshot:
Actually, I canāt figure out how to paste the screenshot I saved on my MacBook desktop. Hereās what it shows:
Preferred Audio Language: English
Preferred Subtitle Language: English
Auto-select subtitle mode: Shown with foreign audio
Hearing-impaired subtitle searches: Prefer non-hearing-impaired subtitles
Forced subtitle searches: Preferred forced subtitles
Hope this helps!
When I followed your instructions as above, the subtitles show up just fine. Why do they NOT show up when I play the movie on my Samsung TV?
In that caseā¦ letās talk about your tv 
Can you please verify what exact version of Plex youāre using on that TV?
Alsoā¦ what model is your tv?
For your convenience, Plex Ninja, I copied what I wrote earlier. That version of Plex is the latest, I believe, for the ReadyNAS 524X. As for my TV, the model number is UN55NU710DF.
Thank you. Thatās appreciated.
Howeverā¦ Iām looking at the player you have running on your TV.
I take it, you have a Plex player on that deviceā¦ or are you playing videos through DLNA?
Also, one more thing, while you are at it, Plex Ninja. I also have a Windows 10 laptop hooked up to the ReadyNAS. Can I install Plex Media Server on the laptop, and use that instead to manage the files? In other words, can I just delete Plex Media Server off the ReadyNAS, and use Plex Media Server for Windows 10 on the laptop instead, in order to manage the movie and music files on the ReadyNAS? Where would the Plex Player be installed in that case?
I donāt even know what DLNA is, so no.
I also donāt even know how to install the Plex Player on the TV, so no to that as well.
By the way, Plex Ninja, since I am obviously able to watch movies on my TV, how can I tell where the player it is using is installed?
Thatās going to be 2 very different discussionsā¦ letās give that a try.
Can you please explain how you get to play the movies from Plex on your TV (kind of from switching things on to playing the movie and seeing it wonāt show the subtitles)?
If you only want to organize things on your server, thereās no need to install a separate Plex Media Server on your Laptop. You can always just open http://app.plex.tv/desktop or use the IP address of the ReadyNAS (http://[IP of the ReadyNAS]:32400/web). This will show you whatās on your server and you can manage your content there.
If you have your laptop āalways onā (whenever you want to watch a movie), you can also move the setup to your laptop. If you have mapped the ReadyNAS to some local drive letters on your laptop, you can still use the file structures from your NAS.
Keep in mindā¦ by simply doing a new install, you will loose your watch history and all manual changes to your library (e.g. manually added / changed posters).
Unless thereās a strong technical restrictionā¦ why not keep the Plex Media Server on your NAS for now? 
In any caseā¦ the player is different from where you install the server. Itās usually an app that runs on the device where you want to play the movies. In case of your TVā¦ itās a Plex client on the Samsung. If you open it through a browser, the player is showing in that browser etc. etc.
Regarding the TV, I turn it on with my Roku remote. Then I scroll to the Plex app and Plex starts on the TV. Then, I navigate to the movie or TV show on Plex that I want to watch, and press OK on the Roku remote. Then I look for subtitles that are not there. LOL
Regarding the laptop, the Plex app does not seem capable of running 4K movies. Plex keeps slowing down. I thought if perhaps I installed Plex on the Windows laptop, it would then be able to run the 4K movies. Does that sound reasonable?
That was the piece I had been missingā¦ you hadnāt mentioned youāre using the Roku as your playback device. What Roku model is that if I may ask?
Thereās two sides to that. The first is the playerās capability do deal with 4K material. If the player cannot deal with what itās presented with, itāll ask the Plex Media Server to transcode the media to a format it can digest.
4K content is generally tricky as itās quite demanding on your player. And also because transcoding it requires a massive load of CPU power (or a server with a sufficiently capable CPU/GPU to do the transcoding).
Long story shortā¦ the ReadyNAS will likely not be able to transcode your 4K content if needed. With regards to your laptopā¦ itāll depend on what HW is built into that device (e.g. CPU/GPU).
Also keep in mind that the media itself is not necessarily to blame. The stuttering could also be due to a poor network connection (againā¦ 4K material is very demanding when it comes to that).
I strongly recommend to have a look at this forum thread discussing 4K playback:
The model of Roku is the Ultra. It checks for new software occasionally, and I think it is up to date. Itās supposed to work fine for 4K/HD. What would be my other options for running Plex on my Samsung TV, so I would not get the hesitation on 4K movies?
Regarding the 4K movies, couldnāt I use my laptop as the server because it would have a much better CPU than the ReadyNAS, which is only rated or 1080P, not 4K?
If my question is answered in the other discussion, I have not looked at it yet. But thank you for suggesting that.
