PowerDVD displays "Critical update for PowerDVD!" message when you are notified every 14 days if there is a new patch available.
Blu-ray Disc and HD DVD titles have adopted AACS (Advanced Access Content System) to protect the digital content. AACS keys are required to play some Blu-ray Disc and HD DVD titles. AACS keys were integrated into your PowerDVD for copy protection purposes. Occasional renewal of the AACS key is required.
