Hi,
as far as I know this movie is produced to be shown on TV not to be distributed on DVD. And further on - as far as I know - the project isn't finished yet.
But Nicholas is right:
Please contact the dojo for further informations.
Ulrike Serak and Max Erikson definitely speak english.
And they know the author of the movie.
I will meet them in about three weeks and ask them myself ...
Carsten
