I bought a Plextor external BD-ROM PX-B120U player which comes with PowerDVD9 BD. I have a Ati HD 4850 video card connected to a regular LCD monitor and a Samsung LE40A552P3R (HD Ready 1080p) LCD TV. The connection to the TV goes via a DVI => HDMI converter and then through a HDMI cable. I run Windows 7 64-bit.

When I play a bluray (I've tried multiple) I don't get any video. I hear sound, but there is no video and I cannot access any of the video options in the PowerDVD options menu. I've run BD & 3D advisor. Now here's the curious part. When I select my TV as the primary screen, I get a pass from the advisor. When I select my regular LCD monitor (connected via DVI cable) as the primary screen, I get a fail because it says it doesn't support HDCP. (I usually use my monitor as primary screen and extend my desktop to the TV to watch movies), but this won't work.

But still, even if I select my TV as the primary display, get a pass (it says it is HDCP compliant, which the Ati HD 4850 should be) but I cannot watch blu rays, no video whatsoever. Also doesn't matter if I only output video to the TV. How can I fix this?


edit: If I output the video signal to the monitor, I get error code 0110 from PowerDVD. Doesn't matter much as I don't want to watch on my monitor, but maybe the error code helps.
