Since I'm the home theater expert on the board, I don't mind answering questions.
Chico, as an expert, how did my explanation of HDTV stand up?
EDIT: LOL at me for being white as snow and not Puerto Rican 
Your explanations of cables and cable tv is spot on.
I appoint you my home theater sidekick. You certainly know more than those over at GPC. I cringe everytime I see an OT: HDTV over there because I know they're going to get bad info.
I was most impressed with your cable discussion. The difference between component and HDMI is overhyped, though you can't upconvert standard def over component due to legal issues. Component is an analog connection while HDMI is digital but they are about equal in quality. In
most cases I can't tell a difference.
The only thing I would add is that you can get dirt cheap cables that are excellent quality at
monoprice.com. I buy all my cables through them.
