I came across this DVD (NTSC). It's some sort of promotional copy with Russian dubbing & original audio (no subtitles).
The covers [open in a new window to see the details]:

A screen shot:
The text is as follows:
"This viewing copy is provided for awards consideration only and is not for sale or public presentation." It runs a few times during the film.
Otherwise, there are three commercial DVD releases of BMM in Russia.
The film title is a literal translation: Горбатая гора - transliterates as 'garbataya gara'.
