Well, I ran into that message for the first time today. It was so bad that NONE of my Blu-ray or ordinary DVDs would work, always returning that message.your display environment does not support protected content
I know the usual causes, and none of them applied to my setup. Thank goodness I found the cause before I did anything drastic trying to get this program to work again. You see up until a couple of months ago it always worked fine. But about two months ago I added a new device which uses your household wiring to create an ethernet connection. Wireless wasn't working out too well for my wife's work laptop. I added this gizmo to give her a better connection. It worked great too. But I hadn't tried to watch any DVDs on my own desktop, which is where I have WinDVD installed. But anyhoo, I unplugged the ethernet gizmo from the outlet and VOILA! the error message disappeared, and my Blu-ray movies worked again.
Some details: I have a Motorola Surfboard Cable Modem/Router which I have my desktop connected to via ethernet cable. My wife's laptop was connected to the router using the ethernet gizmo I mentioned. One end plugs into an outlet near the router, and an ethernet cable between the gizmo and router. In the room where my wife's laptop is located, there is another similar gizmo plugged into the outlet with an ethernet cable going to her laptop. This connection is also encrypted between the two gizmos which communicate with each other using the house's AC wiring. This setup hasn't caused ANY problems at all, until I discovered this HDCP error message was being CAUSED by this?!
Isn't that unbelievable?
Anyway, it is just ANOTHER outrageous mess created by the HDCP How does it even know about other ethernet connections? How much exactly does it know?
