I am about to take the plunge and get an hdtv monitor. i just want to be sure of a couple of things. topic1: Antennas I live in a condo and I do not believe I can mount anything outside. If I get an indoor antena on top of my tv will I be able to receive OTA( I think this means over the air)HD programming from CBS and other networks. the antenna would plug into a set top box and then the box into the TV right? Topic 2 Burn in Can watching nonanamorphic dvds and playing videogames cause burn in? Will I have to stretch them like i would regular cable to prevent burn in. topic 3 speakers is it bad put a center channel on top of your HDTV? thanks in advance for any help! I fell more comfortable asking you guys these questions then any jackass from Best Buy.
