You're welcome, A. I was fortunate enough to attend a retrospective of East-German films last year which also included a few lectures on the pertinent issues surrounding the films. Born in '45 wasn't one of the films I watched, but director Bttcher did attend the event. Perhaps the best film I got to see was Egon Gnther's Der Dritte, which was introduced by its stars Jutta Hoffmann and Armin Mueller-Stahl. Since it's now available on DVD I'll try to write something about it soon 

Thanks for the info regarding Grf.
