Teen Titans airs on RTL2 (crappy German station who specialize in cheap "anime" shows for the stupid kids and cheap "adult" stuff for the, well, adults).

The show started on August 26, airs weekdays around 1:15 PM.

According to reactions in Panini's forum, the dub is awful, which is anything but unusual for RTL2.

German dubbing quality, from good to bad:

Blockbuster movies
TV shows
Animes
