For earlier versions of Apple TV:
- From the main screen of your Apple TV, click Settings.
- Click General.
- Click Accessibility.
- Click Closed Captions + SDH.
- Press Select on your Apple Remote to turn on closed captions and subtitles.
For 4th Generation Apple TV users (newest version): On the touch-sensitive part of the controller, swipe down from the top. That opens a menu that includes "Subtitles". Select "English" to turn on captions for the video you are watching.
Still experiencing issues?
While you are watching a video, hold down the select button (the round button on the remote) for a few seconds and this will bring up a menu for captions. Turn captions to "English" (and not "Auto"). This will turn captions on when you return to the video. This also has to be repeated for every video.
