I have kodi boxes on all of my TVs and play local 4k content 95% of the time, but yea I need sports and live tv occasionally. Websites work pretty well on computers but the streams on kodi addons are very bad, constant interruptions. So I can either hook up raspberry pis runnung raspbian on each my Tvs and have wireless keyboards so I can go to the streaming websites, or I try to get a paid IPTV service on kodi, which I’m trying to do right now.
AntennaPod is great, I used it for years. I eventually switched to self hosting AudioBookShelf which does audiobooks, ebooks, and podcasts. One main reason was because podcasts more and more yank the old episodes and put them behind a patreon. AudioBookShelf downloads the episodes to your server so you always have them. About 5 months after starting using it another one of my podcasts pulled that stunt and I was super happy to have all of the old episodes still.
