mac pro 4.1 (2xquad core xeon) quadro 4000 mac os x 10.6.8
i think the problem is in blackmagic (its an old model), because we try another capture cards (lfg 4, intesity pro) and its OK...
phoenix drivers crashes at cat startup, when blackmagic input is on (i try 3 inputs at the same time)
oh, i forget, this problem appeared after one of osx updates (10.6.5 or 10.6.7 I do not remember exactly)
