Unable to detect Blackmagic Decklink SDI Card #GPU

Hi everyone







I have built a Hackintosh with the following configuration:







Gigabyte GA-Z77X-UP4 TH Motherboard



16GB Corsair DDR3 RAM



3.49 GHz Intel Core i7



Asus Nvidia GeForce GTX 560 Ti 1024 MB Graphics Card







I have successfully installed and am running Mountain Lion OS X 10.8.4 using the guides on this forum and the system is running fairly well, with of course a few glitches here and there.







I am successfully running Avid Media Composer 6 and FCPX on this system. For capturing video, I installed a Blackmagic Decklink SDI card via the PCI Express 1 slot. Initially, I had a Firewire 800 card installed on this slot which was working just fine. I had to remove it to make space for the Decklink SDI.







However, my system does not seem to read the Decklink SDI. I installed all the drivers and software that came with the device. But when I open the Blackmagic Design Desktop Video tool which sits in System Preferences, none of the settings are changeable. Even in my system report, the Decklink does not show up.







I would appreciate any help you can provide. I'm not quite the pro I would like to be with this stuff, so it does kind of need to be spelled out for me.







Thanks.
