The video are stored on a NAS (Synology), the library and JRiver is hosted on a NUC (windows 10)
(ethernet link only- no wifi)

I have no problem playing video with OSMC, via DLNA on the same RPI4, or playing the video via NFS neither (OSMC or Librelec)

On MC29, the default for video is to buffer to "disc", in your case, the SDCard. That will really hamper performance.
Try disabling buffering in MC in Media Network.
You'll lose seeking capabilities on some files but it should be faster.
mp4 files will need to have the MOOV atom at the front of the file. Some do by default, others don't.
There are utilities to do that.

Hendrik:
Disk Buffering should probably be turned off entirely when playing on a local network. Its really not needed, as you can just request what you need from the fast network.

Facel:
Turning off Disk Buffering does not change anything ... still Jerking ith proc at 280% ...
