ASUS U3S6 has been tested and works with the Blackmagic Shuttle. What hasn’t been tested by Blackmagic is Bootcamp. When I installed the card, the USB ports on the back of my Mac LED Cinema Display stopped working. Could it be that be to compensate the bandwidth of USB 3.0? However, it seems like USB 3.0 cannot be handled at its full speed because I got that message. Could my PCIe 2.0 be working as a PCIe 1.0? BlackMagic Shuttle was able to be successfully be recognized and installed, so there has to be some way to make it work.
Anyway, Darren, have you had any success with capturing from BlackMagic Shuttle?
