If your Samsung DVR displays a black screen on some channels despite receiving video sources, start by checking if the camera is properly supplied with power. Then, verify the video output by connecting to the camera's web viewer. Also, ensure the network port is correctly connected and the network settings are properly configured. As a last resort, try changing the hub to one that supports Gigabit.
