What do you think about this blog here about some of the issues and fixes with drivers?^USB3HDCAP if you have USB 3.0 on your computer. It's about $40 cheaper for the same features and more convenient to use (external enclosure and portable). I read it's the same as the $350+ XCapture, except with a consolidated number of inputs and a lack of HDMI passthrough.
