The DVD of Requiem has finally been released in Germany, but the bad news for everyone on this board is probably that it has only german subtitles for the hearing impaired. I am still amazed by the fact that so many german DVD's (even by well-known companies like X-Filme with a potentially large clientele) are released without german subs. In this regard, we proove to be as ignorant as the French and the japanese. 
The DVD includes an audiocommentaryx, interviews with cast and crew, a making of, and other specials, but they are also not subtitled in english.

Maybe some foreign company will also release it in the future...
