A composit video cable is 75 ohm coax. Component video cable is 3-75ohm coax cables. You could use 3 composit cables, no problem!!! Yes the ones that have the 3 video cables and 3 audio cabels make it easer to hook up looks nicer.
But keep in mine if a $25 cable is good a $100 cable WILL NOT BE 4 times better. Good price for 6' component + audio is $30~40. Homes depot has some nice RCA brand cables that will do the job and not make you credit card melt. John
I was reading the boxes for a component video cable and a similar looking composite video and audio cable and could not tell a difference apart from the higher price for component cables and the differently colored connectors. If you use composite cords in the component jacks, would picture suffer? Is there some tuning for video that makes component cables better suited? Curious because I have the distinct feeling that this is a ruse!
