Quasimodo,

Yup, I got it backwards: RG6 is the good stuff, RG59 is economy grade.

Robb,

My reference to coax vs other video cables was meant for simplicity, which is what, imho, I thought was needed to help answer the question. In my experience most people use the term "coax" in the home theater world in reference to RG6 or RG59, not in reference to video interconnect cables, even though they are all technically a version of a coaxial cable.
