I recently purchased the LG BE08LU20 External Blu-ray Disc Rewriter. I installed Windows 7 (64-bit) through Boot Camp on my 27" iMac. When I try to play Blu-ray discs through the external drive on the Cyberlink PowerDVD software, it says that the software "is not able to play the protected content on [my] digital output device". Is there any way to fix this issue? I appreciate your help in advance.
