Or does anyone have a good DVD dealer in Shanghai selling german movies?
This is vague and dated (2005), but a freind of mine took me to the area around Jiaotong University (which campus - I couldn't tell you because the information - sadly - washed over me at the time) had a shop that had one of the best, diverse selections of DVDs I've seen (In Hong Kong, China, Japan, the U. S., U. K., Canada, and Taiwan). I picked up the DVDs of:
Der Schweigende Stern (great East German space opera from the sixties)
Das Experiment (powerful rumination on human behavior from a few years ago)
Anatomie 1 & 2 (disposable, yet entertaining modern day slasher films set in medical schools)
Winnetou I (fun Euro-western from the sixties)
and
Harte Jungs (a so-so teen sex comedy. It was dubbed into English and called "Ants in the Pants.")
My advice is to ask university students, or a friend who knows the university areas well. That's where I was able to get better deals (prices - I bought so many I was able to talk the guy in the shop down to 5 RMB a disc and ended up purchasing 250 discs - 20 of them being the entire series of FRIENDS as a gift to the friend who introduced me to the place, and the other 220 were films that never received official DVD release in the United States, and 5 were defective, but it wasn't worth the time and expense to go back to the shop and replace them) and selection of films.
Happy hunting!
