I happened to catch the longer 210 minute cut of the film when it played the festival circuit (at the National Gallery of Art). The just announced home video release is the mass release shorter version of the film, which is sort of unfortunate since I didn't see any problems with the 210min version... oh well, I guess Kino didn't bother producing a definative video release of the film and include both cuts of the film.
