I am sorry to hear that have had issues while playing 3D content through the on board graphics.
I also appreciate your feedback on this matter. I will make sure your comment reaches the proper department for future consideration.
Thank you for taking the time to communicate this issue to us.
Thanks for your answer.
Yesterday I have tested a 2d bluray and I have the same issue. It's not only for the 3d ones.
I have found a workaround: Use anydvd hd to disable the hdcp check but this software is not free...
