HDCP Problems?

[sinful]

    I'm having some problems that could be hardware or software related. Here is the setup, I'm running a Ceton InfiniTV 6 cablecard tuner through my Gigabyte GTX 750ti GPU to three ASUS VE248H Monitors using 4 Denon HDMI cables. The center monitor is going through a Denon AVR-4310CI Receiver.

    Here Is the problem, when I'm using media center and watching premium channels such as HBO on the center monitor the video goes black but pops in for brief moments but audio continues fine. If I switch media center to a window, everything works great. If I drag media center to the other two monitors everything works great, it's just the middle monitor giving me troubles.

    I suspect that it's a HDCP issue, but I have no clue where to start looking for a fix. I had the same problem a few months ago but was able to get it working, the only problem is I can not for the life of me remember how. the only thing that has changed since then is the Nvidia drivers.

I'm hoping one of you guys might know where to start looking.

I was able to find a fix for the solution. It appears to be a nvidia issue that happens when going from the HTPC through an AVR and into the the monitor. I'll post a fix for the problem for anyone else running a nvidia card through an AVR and getting the same problem.

1. Open NVIDIA Control Panel.
2. In the Display category, Select Adjust desktop color settings.
3. Select the AVR from the listed displays.
4. Under the Apply the following enhancements section, change the content type reported to the display dropdown menu to Full-screen videos.
5. Apply Changes.
