A few words of advice:

Don't use coaxial cable (in a home-theater video situation) if it is at all possible to avoid it.

I am by no means a professional or expert in electronics; however, just based on my own experiences, switching from coax to a composite video setup greatly improved picture quality on just about any VCR I've seen. (Composite video is the yellow one in the red (right audio), white (left audio), and yellow trio that make up a set of RCA connectors for a VCR or something)

Of course, if available, S-video or component video are far superior options, but almost anything is better than coax.

Clarification: I was called on the fact that composite and S-Video and everything else are also run over coaxial. However, what I'm talking about here as coax is VHF, which is what most non-EE types mean when they say coaxial. At least in California.
