Okay I've pretty much read all the post on this subject and still I was left confused. Through a lot of trial and error I'm 100% certain that there is only one way to do this and here's the method... How To Turn OFF Amazon's Closed Captioning or Subtitle Default State... From your Tivo Roamio launch the Amazon Video app Select a Movie (not a TV show) Across the top look for this list... Overview Customers Also Watched Cast More From IMDB Captions Highlight Captions and press Select Highlight Captions Off and press Select Now go back and watch any Movie or TV Show without Closed Captioning Now for the bad news. Every time that you turn on the Closed Captioning while watching a Movie or TV Show that becomes the default again. I tested this in every possible combination and found that to be case in every instance. In each scenario I've had to follow steps 1 - 6 above to change the default state to not show Closed Captions by default again.
