GoPro 3 and Hyperdeck Shuttle 2

Am struggling to work out how to get the Hyperdeck Shuttle 2 to record the live HDMI output of my new GoPro 3 Black. At the moment the best I can get is a green video ??

Is this anything to do with the fact the Hyperdeck records YUV and the GoPro outputs RGB ??

Is there a setting I am missing ??

You need to check the resolutions match between the camera and the recorder. 1080i 50 if prores on the deck. Action cameras tend to have strange sizes and frame rates.

Sounds to me like the Go-Pro is outputting HDMI as RGB and the Shuttle HDMI only accepts YUV. HDMI Monitors usually auto detect and display accordingly.
