I have downloaded the 5.1.2 drivers for the Blackmagic card again (I mistyped earlier saying I had 5.0 drivers). Initially the update did not work However, after going in and looking at the device drivers individually.. something happened where there was a mix of 5.1.2 and 5.0 drivers.. The conflict seems to have confused FCP and thus the control was not being given to the deck & blackmagic output. At the moment, things appear to be working. BTW.. I was using Blackmagic 8 Bit Uncompressed Timelines…with BM 8Bit encoded video. And I rechecked the deck and Device control so that they matched up (which they did). Thanks for the quick help and suggestions. – Ben
