This is an opera in Checkoslovakian without any sub-titles, which is unheard of in the world of opera DVD's. Typically, every DVD comes with a main screen where you do choose the sound, the sub-titles, the scenes, etc. This Blu-Ray has none of this and again no sub-titles in any language. Normally an opera DVD will give you a choice of sub-titles in five or six languages. This is a pity, because just watching the beginning, I could tell that the mise-en-scene was quite interesting. I am returning my purchase.
