Have you checked other channels if they are also having the same issue?
In some cases, removing then re-installing the affected app may help. To ensure the process is successful, make sure to restart your device before adding the channel back in. We would recommend doing this from the Settings menu by navigating to Settings > System > System restart > Restart.
Roku Ultra: no HDR, Plex movies buffering constantly but ok on another setup
Sorry, I've combined two issues into single post, because I am not sure they are unrelated.
Created a Plex Media server on a Raspberry Pi 400, connected to a portable 5Tb Seagate HDD. I have a RAM disk setup on the Raspberry to help with any transcoding. At home the Roku Ultra (latest model) is connected to the server via Ethernet and the Pi connected via Wifi. At Home I have a LG OLED screen. All movies display just fine, little to no buffering or if so, only at startup. I can watch the movie without interruption.
At grand kids home, they have a Sony TV, new. I got them a brand new Roku Ultra. (They had an older Ultra model.) Their TV the Roku recognizes as 4k HDR10, but no content that is HDR displays as such (not sure if this is universal, but no "HDR" notification in the upper right corner comes up). Difficult for me to determine if 4k content is actually displayed as such. BTW, the dad has told me that 4k content from Netflix is "dark,' which tells me that he may not be getting HDR from his Netflix channel, either.
Also, even when the ROKU is connected via ethernet and the little Pi media server is connected via ethernet (i.e. no wifi issues), the Plex movies buffer all the time, especially if over 12mbps data rate. This of course can create a problem if I lower the playback rate, because transcoding kicks in on the lowly Pi computer which cannot handle it. The best measure is to play at the "original" data rate.
I understand that some of these issues may require a post on the Plex forum, which I intend to do, but some may be issues with the Roku setup.
Hello everyone, over the past few months i have had a very annoying issue that has plagued my roku streaming stick while trying to play media from my Plex server. Every 10-20 minutes i will have to restart the stream due to the client getting stuck buffering at 33% and eventually erroring out. I should start by saying that i have no issues getting any type of media to play on other devices and that this issue only seems to happen with HEVC media. Below i have attached a sample of the error logs i have grabbed from the Plex channel that i believe to be important to solving this issue. Any help would be greatly appreciated, thanks!
This was happening to me from time to time. I found that while it’s stuck at 13% I would press the down arrow and then press the left arrow and press okay on the caption menu and select off. Each time I did this the buffering would begin to climb and movie would began to play. Hope this helps.
