According to the dvdcompare website, the German Blu Ray has a Polish soundtrack and subtitles. Is is very vague and does not say if all 6 films have that soundtrack or not. I would only believe it if someone here could actually eyeball the set for themselves and confirm what the discs contain.

The same applies to this for the Quebec soundtrack and subtitles

Ignore that last bit as it is PT only. Sorry!!
