Problem with blackmagic intensity pro and BoinxTV

Hello everyone,
I own a blackmagic intensity pro that I connected to a Mac Pro early 2008 In blackmagic media express I display the screen of the computer that I have connected to the card. While in Boinx tv says that the card is connected but not available. How can I fix?

Please make sure you have Media express closed before you start BoinxTV, otherwise BoinxTV doesn’t get access.
Then make sure you don’t select the “Blackmagic” device in BoinxTV but the one matching the input resolution.
In essence the same as here: http://docs.boinxtv.com/connect_cameras_using_a_blackmagic_ultra_studio_mini_recorder
