Could you describe the problem you're having a bit more? I'm not seeing anything immediately incorrect in the video you linked. The UI page shown on the video is the area / user detection page which displays the Kinect's feed from top down perspective. If you place the Kinect somewhere and go stand in front of the sensor, this UI page will show your location relative to the sensor. You can read more about this here.
If you're seeing some issues with the feed, please submit a video with the sensor's main page with the live feeds visible. This will give a better idea to us about what's going on.
