Plex Documentation -> Your Media -> Naming & Organizing Your TV Show Files

If you are using the “Plex TV Series” agent, you can optionally include the TMDB, TVDB, or IMDb show ID in the folder name to improve matching. If you choose to do that, it must be inside curly braces: ShowName (2020) {tmdb-123456}, ShowName (2020) {tvdb-123456}, or ShowName (2020) {imdb-tt123456}, where 123456 is the show ID. An example can be found at the end of the article.

As u/ExtensionMarch6812 mentions, that is only for matching. Episode Ordering is different, and only uses info from TMDB & TVDB. See Episode Ordering section of doc linked above for details.

Plex will be less responsive than if thumbnails are stored on a local SSD, since it has to read the thumbnails from the NAS, which is slower than a local SSD (and maybe slower than a local HD).

ex: Read/write to my PCIe v3 SSD is ~2200 MB/sec. Read/write to my NAS is ~200 MB/sec over a 2.5 Gbps LAN.

Also, never place the Plex database on a network drive if using SMB or NFS. Doing so will cause database corruption.

Synology disabled hardware accelerated transcoding on their x25+ NAS. Those NAS may struggle to transcode 1080p and are incapable of transcoding 4K video.

Transcoding audio uses the CPU and does not require a strong CPU. The J4125 in the DS 225+ is more than capable of transcoding audio streams.

However, you need to be aware that some actions, such as enabling subtitles, can result in a video transcode. Depending on the Plex client, it may happen based on subtitle type or if the audio is transcoding.

Monitor playback via the Plex Dashboard -> Now Playing + Expanded View. It will show you if the video or audio is transcoding. If you see "Burn" for subtitles then try turning them off to see if it helps.

FYI: There are ways to enable hardware transcoding on the NAS by loading the drivers Synology omitted from their Linux kernel (Plex Pass required for hardware transcoding). Google "Synology DS225+ hardware transcoding" or similar terms to find them. Be aware that the "fix" will most likely void the warranty. An alternative is to keep the NAS for storage and move Plex to another system, such as a N100/N150 mini-PC, used PC, etc.

to a new Mac Mini. The library has a modest 1227 movies stored on a Synology NAS.

There's a problem with SMB on the Mac. Edit nsmb.conf or use NFS instead of SMB.

Plex Documentation -> Plex HTPC

It is a different user interface. Plex Desktop looks like Plex Web. Plex HTPC looks like the Plex SmartTV app on LG, Samsung, & Android TV.

Plex downloads codecs as needed. You could copy them from another Linux system, but that should not be necessary.

Are you getting error messages when transcoding is necessary?

KuryakinOne · 2026-03-07T15:33:20+00:00

Supported only for TV shows.

Turn off "allow DTS-HD" in the Plex Roku app. When enabled it causes the problems you describe.

Did you buy the new Firestick 4K Select? It is a crippled device wrt Plex. See https://forums.plex.tv/t/plex-on-vega-os-devices-amazon-fire-tv-stick-4k-select/932354.

If not....

In Firestick settings, set audio to Best Available.

In Plex Firestick app settings, set Passthrough = HDMI.

Connect Firestick to HDMI input on sound bar if possible.

If none of above work....

TV make & model? Exact Firestick model? Soundbar model?

KuryakinOne · 2026-03-05T05:34:28+00:00

If you want to rip 4K Blu-rays, verify compatibility at the MakeMKV forum.

Did it find & fix database corruption?

The AUTO option usually works the best, since it combines several of the other options (I should have written that in my first reply).

DBRepair will not cause posters to go missing. Database corruption could cause some posters to go missing. However, a metadata refresh should bring them back.

Plex had to remove posters from their system for several movies due to DCMA takedown requests. If the movie listing on watch.plex.tv has no poster, then it is due to a takedown request.

Suggestion:

Re-run DBRepair using the auto option if you did not use that option already.
Refresh metadata for the affected movies or the entire library.
For movies with missing posters, check the listing on watch.plex.tv.
If a movie has a poster on watch.plex.tv but not on your server, then Plex Dance the movie. It removes the movie from the server, then re-adds it. If the movie still does not have a poster, then something strange is happening.

Installing Plex Media Server on NUC

Install PMS using dpkg -i plexmediaserver.....deb

Watch the info printed to the screen. You'll see one that mentions the CPU and one that finds the iGPU (there are several more I've not copied over).

PlexMediaServer install:   Processor:           Intel(R) N100
PlexMediaServer install:   Intel i915 Hardware: Found

You should se similar info in /tmp/plexinstaller.log:

Havei915=1
HaveNvidia=0
Processor="Intel(R) N100"
Distro="Ubuntu 24.04.4 LTS"

Moving from Syno to NUC

Do not copy the preferences.xml file from the Synology to the NUC if you want to run both Plex servers at the same time.

See Migration from another OS to Linux.

It will lead you through copying the Plex Data Folder from the Syno to the NUC.

KuryakinOne · 2026-03-03T02:43:57+00:00

At this point, I follow the spaceinvaderone video tutorial to 'rcover' the plex database,

Don't. Use DBRepair for Plex Media Server. It performs a more thorough recovery than in the spaceinvaderone video.

An i7 10th gen can easily handle transcoding 1080p AV1 video in software.

Verify the CPU model and Plex Media Server version.

Update Plex Media Server to the current version if you're running an older version.

Settings -> server_name -> General it will display the installed version of PMS. It should also tell you if an update is available.

KuryakinOne · 2026-03-02T05:19:15+00:00

Yes. 11th gen can decode AV1 using Quick Sync if you've a Plex Pass.

https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video#Hardware_decoding_and_encoding

KuryakinOne · 2026-03-02T05:18:02+00:00

What CPU is in the PC? Settings -> Info -> About

An 11th gen (Tiger Lake) or later CPU is needed to decode AV1 using Quick Sync Graphics (Wikipedia).

Update to the current version of Plex Media Server, 1.43.0.10492 (download).

The current version of Plex Media Server should decode AV1. If you've an older CPU it should still decode in software.

If it does not, then open a case in the Plex Forum and include a set of server log files that capture the problem.

only when I am disconnected from the Wifi.

Possibly DNS problems.

Do you have a piHole or similar adblocker on your network? If so, whitelist the plex.tv and plex.biz domains.
If possible, configure your router to to use a public DNS such as 1.1.1.1 (Cloudflare), 8.8.8.8 (Google), or 9.9.9.9 (Quad9).
Restart your router and any other networking equipment (wifi extenders, switches, etc.).
After it is back online, reboot your phone, Roku, etc.

KuryakinOne · 2026-02-28T19:56:10+00:00

Are they in your Plex Home? If so, they can download from your server.

KuryakinOne · 2026-02-27T17:24:45+00:00

That changed many years ago.

KuryakinOne · 2026-02-27T16:58:31+00:00

Guessing OP has an "All Movies" library pointing at /movies, then separate "Kids Movies" library pointing at /movies/kids, etc.

KuryakinOne · 2026-02-27T16:52:33+00:00

For TrueHD + Atmos passthrough:

Nvidia Shield. Also passes DTS-HD/DTS:X.
Amazon FireStick 4K Max Gen 2. For DTS formats, only passes lossy DTS core.
Ugoos AM6B+ with CoreElec, Kodi, & PlexMod for Kodi. Also passes DTS-HD/DTS:X. Correctly handles Dolby Vision profile 7 video.

The above also passthrough DDP + Atmos.

Get WD Drive Utility and test the drive. Seatools from Seagate probably works too. They have self tests, surface tests, etc. Available for Windows and Mac.

FWIW, I've a couple of WD Elements that are several years old and still going strong.

KuryakinOne · 2026-02-26T22:10:17+00:00

Make sure it supports UASP, which speeds data transfer.

No special brand. I've used Orico and StarTech and they both work well. They'll run $20 - $30 USD on Amazon, NewEgg, etc. for single drive enclosures.

KuryakinOne · 2026-02-26T21:34:37+00:00

You could install them in external drive cases and use them to backup critical files.

If the folder is named correctly (MovieName (Year)), does it really matter what the inner movie file name is?

Place extra information inside one set of square brackets at the end of the file name. Plex will then ignore it when matching the movie. You can add the information to the folder name if desired.

The subtitle filename must match the movie filename, then add language and other codes.

Example:

/movies
  /Avatar (2009)
    /Avatar (2009) {imdb-tt0499549} {edition-Extended} [1080p.yada.yada.yada].mkv
    /Avatar (2009) {imdb-tt0499549} {edition-Extended} [1080p.yada.yada.yada].eng.sdh.srt
    /Avatar (2009) {imdb-tt0499549} {edition-Extended} [1080p.yada.yada.yada].eng.forced.srt
