Apple tv weird audio and subtitles

TV shows in France may be available in two language versions, as different items in the Store, or sometimes only the dubbed version. TV shows in Canada are often available in two language versions, as different items in the Store. Verify which versions are available and which version you purchased. The supported languages should be listed for each title. If you purchased the wrong version by accident, then contact the iTunes Store staff to correct that.

Hi natanezra,

The default language of your Mac will be used for audio and video in apps that support it, like the TV app.

If you'd like to tweak this there area few ways to do so. First, you can change the language you prefer int he TV app itself: Change subtitles or languages for videos in the Apple TV app or iTunes Store

On Mac or PC

1. Move your pointer over the video.
2. Click the Languages button .
3. Choose the language or subtitles that you want to use.

Learn how to turn on CC or SDH by default.

You can also adjust the language of an entire app where supported in System Preferences > Language & Region. Select the Apps tab then the "+" button. Select the app and language you prefer from there.

Take care.
