USB Capture DVI Plus can capture an analogue composite (CVBS) video signal by connecting the composite cable (yellow) to the (green) Y input on the YUV component breakout cable. Any analogue audio can be captured by connecting it to the mini-jack input. The required firmware version is 2.5.6447 or above. Unlike DVI/HDMI/VGA/ or component signals, a composite signal cannot be automatically detected by the USB Capture DVI Plus because it shares the same connection as used for component video, and is too similar in format. The default setting for the USB Capture DVI Plus is to automatically detect the input signal, so users must manually disable this function. If not, the captured video will be black and white - equivalent to the luminance signal in a component connection.
