I have some ancient desktop that accesses media on my NAS. I run Plex on the same PC no problem. Stopped running Jellyfin because of the above-mentioned issues.

Jellyfin always irrecoverably crashes for me over time. It also suffers from permissions issues where videos won’t play sometimes due to a a transcode folder being full or something like that.

I want to use it but it always breaks.

No it wont. Normal people are tired of being preached to when they are at a football game of all places. Ironically sports were at the vanguard of improving race relations in the United States. There’s something to be said for showing rather than telling.
