I was talking to a friend in Germany who said the German language interface doesn't give creators those options yet. And that's the thing that really gets me. I click on a video by a German, in the German language, expecting to hear German. But instead a high pitched synthetic English voice comes out. Don't get me wrong, I loved all the obviously dubbed B-movies from the 70s and 80s, but it's jarring to hear ARD commentators not speaking German.

Aha. This works. It defaults to German for German language videos and even gives you the option to flip over to English if you want to. That's much more sensible.
