PowerDVD 8 doesn't play DVD's from HDD [Locked]

Hi there,

after updating to CIS 3.8.65951.477 I cannot more play DVD’s from the HDD wit PowerDVD 8.0.2521.50.

Uninstalling and new installation of PowerDVD doesn’t solve the problem.

OS: Vista Home Premium 32 Bit, Service Pack 1 and all Windows updates.

Any Idea?

Thanks.
