Have done some further testing

It seems that it IS possible to use more than one Decklink Card in a MacPro with the correct drivers

have just successfully tested a Decklink HD Extreme AND an intensity Pro - both work and allow video input on each card.

It also seems that it should be possible to use 2 x intensity/pro cards in one system. The drivers DO support it.

Will be testing HD inputs on these cards next week to see how many HD inputs are possible at one time - there may be some limitations...

These Decklink cards also work with either a Phoenix or LFG capture cards in the same system at the same time - in Standard Definition (HD tests next week)

Test system:
2007 MacPro 3.0G 8core, 8G Ram, 500G SATA, X1900XT
