I noticed the age of the interviews after replying - kinda sad, reminded me of forums I joined around that time, and have since dried up as technology evolved. I actually ran opensuse for awhile around that time too (it was not very polished) - shame I didn't know about the interviews then.
Nowadays I run a Fedora-based distro called Ultramarine - which rocks! Fast, smooth, stable, versatile. Small but knowledgeable and very friendly Discord-based support. Sponsored by a small startup called Fyra Labs. I thoroughly recommend checking them out.
There is a alpha client and instructions available here: https://smartdigihere.com/jellyfin-on-samsung-smart-tv/
However as stated further down the article, it's easier to just use a web browser and access your jellyfin server that way. Login, bookmark the URL (don't forget to include the port) and then hit full screen.
Note: You may need to tweak (server side) your transcoding and subtitle settings.
