I just recently purchased a new samsung smart TV. I installed the the latest plex app, logged in and tried to play 2 newly added movies but for some reason it doesn’t play them. I have tried on the mobile app, ps5, fireTV and they play just fine. I am only getting the playback error on the samsung T…

+1 for me. I tried allowing insecure connections and it didn’t work. Then I changed language from English (UK) to English and it now works. I’d been trying to play a 4K HEVC file.

Update: Re: the “Unsupported multimedia file format” problem (not the connection-related problem) Some of my users say it’s working ok now. They can play my mkv x265 files from my Plex server on their Samsung TV’s. I can see them playing the content from my Plex dashboard. I haven’t updated …

Setting insecure connections on my one Samsung TV seems to sort the issue but not on the other. Guess we’ll just have to wait for another update :unamused:

I too am experiencing this issue. Everything played fine, and then there was an update to the Plex Player for Samsung TV and now there’s a growing handful of files that don’t want to play that played fine last year on the same TV with the same settings. I’ve tried fiddling with quality settings, but…

I had to set both the server and TV to insecure to get my mothers TV working again, on the server preferred was not enough, it had to be set to disabled.

We need a fix! This must be an priortiy.

Issues here playing MKVs that worked perfectly fine either direct play or transcode before all of this. I get hit with the ‘multimedia file format not supported’. I can play MP4s okay by the looks of it. I have a UE32M5520, latest firmware, plex app 5.25.3 platform version 3. I can gather some logs …

Any update??? We cant use plex properly. Please give us any information about this problem. When will come TV ap update?

Samsung just released a firmware update for my TV and it DOES NOT include the new letsencrypt root certificates. Never buying samsung again.
