DIY s-video cable: is 75 ohm wire essential?
I'd like to make an s-video cable for the TV & DVD player in my bedroom using some cat-5 cable. The specs for the cable is 9 ohms/100 m. I've seen a lot of component and video cables being advertised as 75 ohms. Will the difference in impedance make any difference or damage my equipment?
Also, I understand that the 4 pins in an s-video cable correspond to Y, Y-ground, C, and C-ground. I take it that, theoretically speaking, I could just jam 2 stripped strands from the 4 cat-5 pairs into where the pins would otherwise go, and this would work. Is this right?
Thanks in advance.
