Ubuntu, and the experience was crap lol.
Then I got to try Debian on a server and it was much nicer.
Then I saw Torvalds uses Fedora, and given that he also disliked Debian and Ubuntu for their lack of end user ease, I switched and have been happy ever since.
Seriously though, GNOME 40 really should not be the default DE. It made me think Linux UI was years behind Windows when it was actually the opposite with proven DEs like XFCE, KDE, and GNOME 3/2 etc.
Does jellyfin do untranscoded video/audio?
Haven’t used it in years but finally building up my media server again and I remember it had some funky settings for hardware encoding back then which I didn’t need because I was connecting to it via a repurposed gaming laptop that could easily handle 4k content and surround sound by itself.
