Video has a DC component and a much wider bandwidth, so it's important that not only is the DC preserved, but also that correct matching of the impedance of the cable to the sending and receiving equipment is pretty exact. You will see 'ringing' at the edges of objects as reflections in the cable spoil the image otherwise. > Or is there a better way? The professional TV industry uses 75 ohm unbalanced co-ax to transmit video. > We will probably have a "multimedia PC" adjacent to our home entertainment > centre and I was considering running audio and video cables from my PC > station to the entertainment centre also. > > Any better suggestions? > > Rob -- Sincerely etc., Christopher Sawtell
