I used Plex about 12 years ago. The first time my internet went down, and I couldn’t use it, I stopped using it. Garbage. Not what I wanted.

I used Windows Media Center as long as I could, I loved it. But, eventually, I had to leave Windows 8 behind. Now I use Jellyfin and SABnzbd, it works okay most of the time, but I don’t serve media to the outside, so I don’t know if it works for that.
