APPLE TV CLOSE CAPTION OR SUBTITLES

iTunes supports only very few movies and shows with close caption or subtitles.

It is surprising since there are so many other features on Apple products designed to assist those who are differently abled.

If the video supports it then it is available. You can turn on closed captioning in the AppleTV settings. Go to Settings > Video.

I'm afraid not, until iTunes rents/sells movies with such capability. In settings, I have subtitles and cc turned on permanently, but have never found an iTunes movie where they appear. Let's hope Apple reads and fixes this, since it's a major shortcoming.
