Highlander Trailers on the web but ...?

Starship Highlander (Aug 31)
Robert Amper, the creator of "Raumschiff Highlander", made the first of this German language series of five witty satires on Star Trek way back in 1995. "Starship Highlander" is ample proof that our European cousins have always been creatively and technically up there with the best! The website has downloads of the Trailers but could anyone enlighten me on how to find the full length productions?
