Video Cables

I don't have any knowledge about S video cables, AV switches, video connectors, etc. When I bought my home theater and LCD TV, I asked my friend to set it up for me. I mean, I only know how to flip on channels but to interconnect the cables and what have you, forget it! I could make an electronic explode with wrong interconnections. I know it's crazy but for me, that's a man's job.
