If you want to clear out any stopped containers, orphaned images, networks, etc run “docker system prune”

What I think is happening is there is a persistent volume mount that needs to be cleared out. If you’re using the docker run command with a -v flag, check the host path. It’s likely there are saved configurations you’re passing into the container.

I’ve used Chromecast, Roku, Amazon fire, and most recently the jellyfin app on my Google tv. My order of preference would be: Android/Google tv app, tie between Roku and fire stick, Chromecast

All of which jellyfin also does, just for free
