Hi, I am trying to calibrate the intrinsics of my Kinect but when a subscribe to the IR topic /camera/ir/image_raw all I can see is a black image. So I tried viewing that topic using ImageView ( **rosrun imageview imageview image:=/camera/ir/imageraw)** and it is not working either; but I can see the images of that topic using rviz so I can't figure out what is going on.

Because I can see it using rviz I assume is not a problem of the driver (I tried freenect and openni), someone has any idea on what to do?
