My daughter is always finding features I’d never heard of. I’m sitting there, watching the Katy Perry movie with her. She hits some random buttons on the Apple TV remote and a screen comes up and then disappears as quickly as it appeared. A screen I’ve never noticed… Flash forward to later in the day and suddenly the subtitles for Lillyhammer are in Spanish. Now, my Spanish just isn’t as good as it used to be. So here I’m wanting to switch it to English. But, where’s the setting? I finally found it by browsing to Settings, then Audio & Video. Then browse to Closed Captioning and switch it to English, or just Off if you’re only looking to see captions when something is in another language. This caused me to start trying every possible key combination (with only 6 keys it didn’t really take that long) until I held down the Play button for a few seconds while inside Netflix and streaming a movie to my Apple TV. This brought up a menu allowing me to select the Closed Captioning language. Fun stuff. Good luck!
