I deeply regret that German television is in German language.
Once upon a time, when Britannia Ruled The Waves, they had the manners to respect foreigners and their languages.
Regrettably, these aren't continued by some.
Mind you, you are a foreigner yourself, almost everywhere, and can't rely on being understood. (less than 20% of the world's population speak English, acc. to Wikipedia)
Have a nice day.
