unable to copy DVD to HDD - wrong region code?

[LAZA]

i updated my machine from Natty to Oneiric:
now i'm not able to copy my original DVDs to HDD, always get this message:

Fehler beim Abrufen eines Schlüssels für die Verschlüsselung. Das Problem kann durch eine der folgenden Methoden gelöst werden: Durch Einstellen des richtigen Ländercodes für Ihren CD/DVD-Spieler mit dem Befehl »regionset /dev/sr0« oder durch Starten von Brasero mit »DVDCSS_METHOD=title brasero --no-existing-session«.

starting Brasero with the mentioned command, i have the same error and get this on CLI:

$ DVDCSS_METHOD=title brasero --no-existing-session
