Here is the video page for last night's feature on Maruhn's in Darmstadt. You'll need some decent German to get by, I think. Select from the right hand side, "Der größte Getränkemarkt der Welt". http://www.kabeleins.de/tv/abenteuer-leben/videos/folge/freizeit-1.64465 It's more about the shop than beer, but some good stuff nonetheless.
Really? lol, GEMA blocks just about everything from being shown over here I didn't realize it went the other way as well. Nothing too exciting, really, just a 10 minute clip of a guy running his shop.
