have you ever seen this:

https://www.sendspace.com/file/b7ez31

i thought it is a new dump....but it matches: http://redump.org/disc/17488/   even when it is completely different named here in Austria.

Buzz! - Das große Länderquiz (or should it be called "Buzz! - Das große Österreich Länderquiz" ??)

RINGCODE:
Sony DADC    A0101089791-A511 16
Toolstamp: A03
IFPI: IFPI L556

at least it confirms the existing dump to be good...

Some releases have different names across Europe

SCES-55387/AT

The bold part is what matters for difference.
