We would need a dedicated app for Android TV synchronized with a Nostr account and possibly with subtitle search on opensubtitles 💪

I mean a thing like this:
If you just make "that but Nostr based" there isn't much hope, lots of solutions like that have existed for years and work great, no Nostr needed.
If you could integrate a social component, like movie curators, watch parties, popular with your Nostr group, stuff like that I think you could be onto something though.
Stremio is open source, so adding Nostr plugins or sign-in could be possible.
