I bought a used H920+ and cannot get video to record from the CGO4. I have control of the yaw and tilt, can take pictures, but cannot zoom or record video. When I press the video button I get a red warning at the top of the screen "Please do not operation in this mode". I tried resetting the camera, formatting the card, re-binding the camera. I have a U3 SD card in there, which I may buy a new one to see if it continues. Anyone ever seen this?
