I reinstalled PowerDvD9 following the instruction given by the support ( mail support ) and applied the patches ( see my first post for the patch details ).
I still go the message "Cyberlink can't read the content because it is corrupted" but if I play a BR disc that works stop it and try again with the previously non working BR disc it works.
This issue is very strange.
Update 2 :
My "trick" doesn't work. I tried again and it failed.
