HDCP Error When Running Cloned Screens...

[SlaughterX]

So, I have an my PC connected to my receiver (Onkyo TX-SR605 via a Radeon 4870) which is connected to my TV (Samsung 40C650), all through HDMI. In the past I could not use cloned screens (displays the same screen that shows on my monitor on my TV) when watching BD-ROMs, but more recently I have been able to (for example, Tron works fine). However when I tried to watch Battlestar Galactica it gave me an HDCP error during the episode prologue. Now everything in my set-up is HDCP compliant, so I shouldn't have any issues. I am running CyberLink PowerDVD 7.3, and ever since they removed HD-DVD support with their last update I am convinced that they are purposely ****ing things up, as I am experiencing more problems now than I did in the past. Does anyone know what is going on?
