My OWC dock just showed up today and connecting my older Cinema Display (DVI) using an Apple DVI to HDMI adapter results in a flashing blue screen. The display is detected, it just flashes every few seconds. I'm guessing this is some sort of HDCP handshake issue. I just sent a note to OWC, just curious if anyone else has had the seem the same problem. Or if someone can recommend a different dock for connecting the display (not sure if Displayport to DVI will have the same problem).
