(1) Are all your components (GPU and Monitor) HDCP enabled?
Cyberlink has a program that will verify your system compatability.http://www.cyberlink.com/prog/bd-support/diagnosis.do
AnyDVD circumvents the DRM encryption to allow Blu-ray to play on a non-enabled system.
They also have a trial version that you can try.http://www.cyberlink.com/products/powerdvd/overview_en_US.html
My self I use the Cyberling version on two desktops w/blu-ray writers and total theatre on my to laptops with bluray players.
Links at to US versions, Not sure if a difference base on country ( DVD code region)
