Nuvio MV

Nuvio MV is a TV app for one household and the family it's shared with. It lets the household's TVs share their own setup (Live TV playlists, settings and sign-ins to services you connect) through the household's own Google Drive or Dropbox, instead of a third party's server.

This site also passes Dropbox sign-ins from a phone back to the TV that asked for them.
