I would think that you will only be able to interface the KN7000 Video out to your PC card, if the card has a 'Composite Video' input - that is one which accepts the combined signal of Luminance, Chrominance and Synchronisation signals.
It is also worth checking the video format is correct (PAL/NTSC)see page 186 in the KN7000 manual. If you want the sound through your PC as well, you can of course use the USB link.
