I torrent to my laptop to watch films and shows (VPN with a killswitch). Want a dedicated setup so bought a Raspberry Pi 4b thinking of KODI setup. Is KODI the way to go, or is there a better way to stream or download movies via the Raspbery Pi4? What can you suggest for my home-made box to replace Disney, Netflix, Amazon Prime etc.? Looking for safe pointers and hopefully can search for the "how to" parts if needed.
I can recommend the dietpi OS; it is a minimal os that comes with a package manager for installing containers for things like radarr, sonarr, deluge, and jellyfin, which will allow you to download/watch movies(find on radarr, download with deluge, watch on jellyfin) and tv shows (find on sonarr, download with deluge, watch on jelyfin) in a fairly autonomous way. Its a bit of setup if you havent done it before it might not be for you but once its running its fairly seamless.
I have a very similar setup, but I recently switched to using CasaOS on top of the DietPi. It comes with docker compose presets for all the arr apps, and also creates a homescreen with icons for all apps. I was doing this using a bunch of different services before, but CasaOS bundles it all together.
