Delay in Playback Start After Skipping Forward/Backward

nope, nothing other is running, this happens since I can remember, there were versions of Infuse that didn’t show this behavior, and as I said, I have no problems whatsoever playing the same content from a shared network drive mounted to my Mac using IINA or VLC.
Already after several MacOS installations and such.

Seems that the behaviour is gone when I switched to Emby Server which I installed on the same machine, turned off Jellyfin and I’m now using Emby without any playback start/resume issues…

you clearly missed the information that this DOES NOT happen on players such as IINA or VLC…
