Any ideas?

You see the ~4 dashes above the man's head, and the 1 above the kid's head? those are closed captioning data which is placed at the VERY top of the picture...The bright part of the picture should be ~3-10 horizontal scan lines away, but is is not (it is much farther). Your video source is giving you a letter boxed and pillar boxed signal (you can see the extra horizontal black bar faintly on the left side as well). It looks like the below where the picture is shrunk by the signal source and black is added around the edges (please excuse the lack of right perimeter VK's posting system dislikes ASCII art making a right border impossible).
