Yeah, i’ve got the same buffering ■■■■ on 3 of my xbox’s but it works on my nvidia shield tv 2017 model. Very annoying that you cannot stop and resume another day without the endless loop of death. In the mean time plex is giving me ■■■■ movies and series from the stone age which i have not asked for, what a crap.
So plex do you work and fix this
Aucun problème avec ma Xbox one S, en réseau local via cable ethernet et lecture directe sur Plex. Je passe tout les fichiers 4K HDR. Je comprends pas pourquoi vous avez tous ce problème.
Same issue for me tonight. I was watching a 1080p movie with a DD audio track with SRT sub. Buffering every 12 minutes exactly.
English: No problem with my Xbox one S, in local network via ethernet cable and direct reading on Plex. I play all 4K HDR files. I don’t understand why you all have this problem.
Pourriez-vous s’il vous plaît vérifier si le fichier 4k que vous lisez est en lecture directe audio et vidéo ou s’il est transcodé?
Après beaucoup de tests sur ma xbox one d’origine, c’est à cause du transcodage - généralement parce que leur audio est DTS ou autre chose que Dolby Digitial 5.1 - qui provoque un transcodage.
Essayez également de forcer un transcodage en abaissant la vidéo à 480p ou quelque chose - voir
Il se met en mémoire tampon sans fin pour moi même lorsque je laisse tomber une vidéo 1080p à 480p dans le client XBOX Plex.
Je commence à soupçonner que c’est juste l’acte de transcodage qui cause le problème pour moi - pas vraiment l’audio. Mon serveur est assez puissant pour le faire - donc je n’ai pas de sens.
English: Could you please check if the 4k file you are playing is direct audio and video playback or if it is transcoded?
After a lot of testing on my original xbox one, it’s because of transcoding - usually because their audio is DTS or something other than Dolby Digitial 5.1 - that causes transcoding.
Also try to force transcoding by lowering the video to 480p or something - an check again.
It endlessly buffers for me even when I drop 1080p to 480p video in the XBOX Plex client.
I’m starting to suspect that it’s just the transcoding that is causing the problem for me - not really the audio. My server is powerful enough to do it - so I don’t make sense.
Seemed a bit better for the last month not as much buffering then bam! They release another update and it’s back to buffering every few mins.
Ok, I’ve done a lot of experimentation.
To me it seems like that it’s not the audio or video, but the fact that it’s transcoding. There’s something that the XBOX One doesn’t like about the transcoded stream.
Could some of you please try the following?
When I do this, i get to about 3 skips back and forward before it starts buffering almost endlessly. Which is the same result i get when I stream a file that needs transcoding (i.e. due to DTS or something).
Do you guys get the same?
Also, Just setup a Ubuntu server with Plex Server (other server was windows). And I have the same issue. Definately not the server that’s the issue here.
Last update was diabolical, you could somehow scrape together some kind of manageable playback before but it’s totally f*cked. EVERYTHING transcodes now. They can’t blame Microsoft either this was a Plex and Plex only update that borked it.
It will sit and buffer for about 5 minutes. If you leave it it does start eventually but then buffers again every few minutes.
FWIW, I’m having success (jinx) by combining a couple Plex settings changes from above — specifically, disabling Direct Play while enabling Direct Stream; and, setting Remote Quality to Original.
Setup:
Xbox One-S (cabled Ethernet)
Plex Add-On App for Kodi
NFS Share from Synology DS1815+
Plex Media Server = Synology DS1815+
Test:
20GB MKV video file
1080p with TrueHD Atmos 7.1
Headphones plugged into Xbox controller
Prior to applying the settings changes the test movie eventually played well without headphones plugged in — assumedly, this is where “Direct Play” did its job, because there was no cause to transcode or remux anything.
Prior to applying the settings changes the test movie buffered interminably with headphones — assumedly, because headphones prompt PMS to transcode audio and video (DS1815+ isn’t powerful enough to transcode huge files.)
It’s working perfectly now that Direct Play is disabled — assumedly, because Direct Stream allows for the video to be delivered “as is” while the ECO transcoders successfully remux the audio to Stereo, for the headphones.
After working on this for several days (logs, certificates, IP allocations, ports, etc.) the settings changes produced the first instance of the test movie playing without any buffering — zero.
If this turns out to be a fluke (if the problems return) I’ll probably use our Mac Mini as a second PMS exclusively for the Xbox One-S (which almost always involves headphones) while retaining our DS1815+ as the primary PMS for our Nvidia Shield TV (which is a stunningly capable client, btw. )
Plex certainly has involved a learning curve — we were early adopters, nearly 10 years ago. The recent issues with Plex playback on our Xbox One-S was a whole new level of frustrating. Now, however, I feel like it wasn’t just the Plex app on the Xbox One-S. Because I tried a half dozen media-playback apps on the Xbox One-S, and they all reproduced the same interminable lag. I did toggle the PMS setting to prohibit video transcoding. But it seems like the Xbox One-S kept trying to transcode both audio and video, until I toggled “off” Direct Play in the Xbox One-S Plex client (in the Plex Add-On for Kodi.) Then it just transcoded audio, apparently, because the test movie just started right up, and it just worked.
Fingers crossed. Grateful for the ideas I got here, from all of you. Wanted to circle back after I had some different results from testing (finally!) Cheers.
I’d rather plex and MS just fix the issue, I also think disabling direct play nukes HDR capability
Hi @WilsoniaNAS & @TheNightFox,
Can you double check that your sever is found as “nearby” in the xbox plex client, otherwise it will assume it’s remote which will force a transcode (unless you have remote set to “original”).
If you find it doesn’t say “nearby”, please have a look @ the following, Find the “ DNS Rebinding ” section and read everything below it. One of these options might help you
I had to add the following in my Tomato Router to fix the issue (i.e. it wasn’t detecting as nearby)
rebind-domain-ok=/plex.direct/
@WilsoniaNAS, I will try your settings just incase it’s some sort of weird combination bug.
Thanks to @WilsoniaNAS suggestion of trying the Kodi Add-On, I recently I started getting constant buffering on certain files using the Xbox Plex app.
I use Plex from multiple devices (Android tablet, iPhone, MacMini (PlexMediaPlayer), Apple TV 4K) and none of them are the buffering issue the Xbox app is experiencing.
Setup:
Xbox One-S (Ethernet - AT&T Fiber backbone in Tx)
Plex Add-On App for Kodi
Cloud based Plex Media Server = VPS in Dallas on Ubuntu 16.04 running PMS in Docker
-Media hosted on Google G Suite account connected to Plex via unionfs
I don’t have a 4k TV the same buffering issues apply to playback of FullHD content on the Xbox. A good solution for how but I hope this gets fixed soon, and if we could only get audio passthrough as well 
Whilst waiting for a fix, i’ve put together a script to convert the audio to AC3 for movies so it videos can direct play without the need for transcoding. Not sure if the will work for the 4k movies (it might be another issue), but it works for me on my 1080p films.
I’ve created a seperate post for it so that people could find it easily.
Cheers
Fishy
I keep getting updates for Plex but it never fixes the 4k issues. Is there a changelog or any updates when the xbox one plex app will be fixed?

Yeah not sure Plex can blame Microsoft anymore for the incessant buffering issues we are all having. I’ve been using Kodi on Xbox One now for the last month and had ZERO buffering on any media and this is an old app!!! The faults of the Plex app are the faults of the Plex developers and the Plex developers ALONE.
Nice work mate!
Just wanted to add to this discussion. I’m also seeing this problem on Xbox One X and Plex. Same setup for years (apart from the X used to be a normal Xbox One). PC as server streaming from a NAS upstairs with Samsung Q80R and a 4k projector downstairs linked by Fast (not giga) ethernet. Never had any issues until recently although I’ve only just started getting into 4K. I have the same issues as reported. I can’t get more than 15 mins in to a film. Up to this point its flawless, but then it stops playing, and will never start playing again (even from the start).
I ran a new cable for a gigabit link but no difference. Went back to the old one (as wired outside the house). The fix posted above using Kodi and Plex addon works perfect thankyou for that link I was almost going to buy a shield but I really don’t want to a. spend any more money. b. add another box to the living room when the xbox has been fine so far.
Interestingly, the plex app on my samsung tv also been updated recently and has the exact same issue…and that can’t even direct play most files.
Shame there’s no HDR on Kodi/ plex although this is a good workaround for now. Was very annoying the other night been busy all week sat down to finally relax and instead spent the whole evening trying to get it to work, I came across the kodi workaround at 10pm and although it worked, by then it was too late to watch a film.
I actually prefer the “old”? app though Kodi, its much quicker to start playing movies and just generally feels snappier with no nonsense like plex tv or any of that rubbish.
EDIT: forgot to mention some other things I’ve noticed. Seek also doesn’t work properly anymore. If i try and scroll to a point in the movie, it goes somewhere nearby but out by minutes. Also if you go into plex settings on the xbox (button at the top with your account picture), if I make any changes, I can not go back into settings every again without closing the app down and restarting.
Everything has been working for me for a couple months now, full 4K HDR no buffering…
As of yesterday I’m now getting buffering on everything, 4K, 1080p, DTS, AC3 some 3 minutes some 20 minutes
Plex App Version: 2.52.1.70
Xbox One X: 10.0.19041.2388 (2005.200418-0000)
Plex: 1.19.1.2645
4K HDR Sony TV works as long as audio is AC3 (converting DTS to AC3 with Popcorn MKV Audio Converter)
Normal 1080p content though Kodi/Plex
