Micro stuttering during bitrate spikes in some 4k BD Movies - Nex1337 - 2025-07-11

Hello
I have a problem with the jellyfin server. There are millisecond stutters when playing some videos on the TV when the bitrate momentarily exceeds 110-120 Mbps. The transmission is direct without transcoding, the movies are in .mkv format they are raw copies of my blu ray 4k movies. The TV is connected under a 5Ghz Wifi network, however this is not a problem because I have checked other possibilities.

Here is what I was able to figure out, unfortunately none of the following attempts helped:
- I connected a USB-Ethernet 1Gbps adapter to the TV.
- I changed the Router to another one
- I installed the server on another computer

I also noticed that if the movie is remuxed by the server, the problem does not occur.
Example: if the movie "All Quiet on the Western Front" is played directly then there is always micro stutter in a given minute of the movie, but if I reduce the bitrate from auto to 120mb/s then there is remuxing and through this the problem disappears.

In addition, if the video is played from an external drive via usb connected to the TV, the problem does not occur

Devices Tested:
TV: LG CX
Jellyfin server: N100 R1 Aoostar (Connected by Cable to Router)
Server Version: 10.10.7

If someone could direct me on what else I can do, I would be very grateful.
For any help, thank you!
