Kodi playback stuttering when playing large files

[Host-in-the-Shell]

Unfortunately, like DP, I also don't use Kodi much and abandoned it in favor of other apps that were easier to use, so no idea if tweaking some kind of setting can help. Why it only happens there could be some issue somewhere with the network implementation for Kodi, the jellyfin app, or something like that, but that's just me speculating.

I'd also consider the client; not really familiar with that particular stick, although (I think) I found the specs and they seem fine.
