I want to turn on my TV, have a list of potential movies and TV to watch, click something, have my computer/server DL it on the computer, and stream it to my TV.

Can you really break it down for me? I have Jellyfin on my computer/TV, but I hate having to DL the file and move it myself. I know radarr can do something like this, but whenever I google it, I get a bunch of term I don't understand.
