I suggest that you purchase this, and stop this nonsense with the orignal Kona SD card. I make jokes on the Blackmagic forum on when they will write new drivers for the Blackmagic 64AV (the predecesor to the Kona SD card).
Your card is OVER. Buy a used Kona LH, and have all the wonderful new features that all of us enjoy. A card that AJA will continue to support.
