One thing to note on capture cards is they generally don't have the tuner needed to display the type of signal coming in from a cable hookup. Most have a tendency to be analog and fixed for one channel use. The RCA phono jacks for audio and video confirm that too easily. The tuner card offers the tv group for enabling the 125 channels usually seen on basic cable. The input signal would be one selected from a selection list usually seen in a drop down menu in settings. There you choose the type of input between composite, s-video, or cable.
