DLNA is a horrible experience compared to Plex, just above a network share. Did you know you can install Jellyfin and point to the same storage that Plex uses? That way you keep Plex (in case you bought the pass), and have Jellyfin as a backup.

Interesting

My main complaint with Plex is local searching is hit and miss - a little while back I typed in a string I knew was in the title of a file (confirmed using 'locate' in CLI) and it returned 'no results'

Plex does some wonky things, like missing external subtitles right there in the same video subfolder, or forgetting/failing to detect a compatible video file for some reason. My goto solution was simply to touch the files so Plex would think they were new and index them.

I used extf4 as storage, but changing to NTFS (yuck) has caused less issues. With the last version the search for subtitles is broken, but at least I can add them manually. I bought Plex Pass for life, but stayed with the free version because it's more stable.

I only had a brief test, but searching seems a little better since this update

I'm on the monthly plan because I wanted to play with GPU transcoding - despite what a lot of folks say it does work in Windows on an AMD iGPU, although I've switched to discrete now (previous server was Ubuntu, but Linux GPU fan control seems to be a mess and we all know the Nvidia driver saga)
