hi, german speaks chilean spanish, there is a diferent way to speak a language, depends of the country. so if you want to learn a "neutral spanish" or latin american spanish maybe try with the mexican spanish. about german videos with subtitles I thinks its dificult to find, because the translate its very difficult,like for an example there are some jokes that only work in spanish, also here in chile some people don't pronounce the letter "S" and talk very fast too, so for the people its very dificult to understand, even for the spanish people.
