Hi Which browser are you using? In the tutorial there is a section of different ways in playing the videos. some will automatically just start and with some other browsers it starts a different way.

The page it comes off is http://accessibilitycentral.net/nvda%20tutorials%20for%20other%20programs.html

The subject line that you jump down to by headings is using tubi tv with nvda but has a little on mobile devices with the app. they are more accessible with talk back and have been told voice over and on my samsung tv it works with voice guide. some qwerks but I can live with that.

They are probably more accessible than the web part but if a few people asked them to add short cuts to the player and label  some of the buttons etc a lot of visually impaired people will be happy.

On the link given to where the tutorial can be found there i is a section on starting the movie/show with a browser.

hope it helps.
