Hi, I have an Intensity Pro + a Decklink Extreme 3D installed in my MacPro 1.1 2x2.6 DualCore. Can it be that the PCI bus doesn´t have enough power to capture HD streams via HDMI from both? I get lag, choppy pictures, frame drops, tearing, all sorts of trouble, when both cards are in use.
there are also Problems with BM sdi cards and new macpro's....
it really depends on the slots you use, may try another configuration/combination.
normally this is a osx problem.
does the Cards work in Final Cut or other supported Software?
