Then you of course had a promo because like all Alhambra releases this is not available digitally at all including their 6CD compilation. A good compilation is this 2CD set which is and which I have:
https://www.discogs.com/release/27321039-Enjott-Schneider-Filmmusik
First four films / tracks 1-15 are Vilsmaier movies. Two movies are missing including the sixth and last one SCHLAFES BRUDER after which their collaboration ended. On that Hubert von Goisern was co-composer but there was no actual collaboration as far as I remember. A central piece by Schneider is an huge organ tocctata that is available separately and also source music in the movie.
Thanks for the extra info! Yes, it might very well have been a promo.
