Two things contributing to the dark bars:
1) Whatever your camera is, it's running at 60.00 Hz (or 30.00) instead of NTSC 59.94 Hz (or 29.97). This causes the bars to drift vertically.
2) The shutter duration is too narrow. If there is no direct shutter control on your camera, you could try reducing the brightness of the TV to get the camera to lengthen the shutter time
