Seems a lot more reliable, and allows falling back to the "main" video
in cases which didn't support this previously.
A next step may be to allow every screen to support a video based on its
screen name, rather than specifying the local `TourneyVideo` every time.
Rather than continuing with `ID` or `Id`, this should follow the new
standards and use `OnlineID` instead. Only updating this since it's a
newly introduced class.
