Mountain of Diamonds (tt0151639) not a movie but a mini-series / duration is 400 minutes in four parts

Hi there,

I am owning the DVD set of the mini-series of "Mountain of Diamonds".

IMDB ID: tt0151639

This is listed as a  movie, but it was aired and released as a four part mini-series simultaneously in Germany and Italy. I bought the DVD of it and its four episodes have the following titles / durations:

E01 - Die brennende Küste (German) / 98 minutes

E02 - Der Diamantenberg (German) / 99 minutes

E03 - Wer aber Gewalt sät (German) / 103 minutes

E04 - Flammender Hass (German) / 101 minutes

I even found a couple of release sites from the German release:

https://fernsehjuwelen.de/gesamtkatalog/fernsehjuwelen/3269/gluehender-himmel?number=6412908

(4 DVD set)

It is listed at fernsehserien.de as TV mini-series.

The entries at TMDB / TVDB are obviously "mirrored" from IMDB and do not hold much info - and are very wrong when it comes to format.

Here's the cover/backsides of the DVD set for content:
