When I play a bluray movie on the built-in Bluray player on my HP Pavilion Entertainment PC Laptop with graphics by Nvidia PureVideo HD, it works fine. However, when I connect the HDMI cable to the laptop and the other end of the cable to my DVI port on my TV, the movie stops, stating I am violating a copyright protection: "The content is protected. The content is not allowed to play in the current display mode." Why not? When I exit the player, my PC Screen is emulated perfectly on my TV using those same connections. Is there a setting I must change on my PC? Why is there an HDMI port out on my PC if I cannot use it?
