Could someone please explain to a "beginner" why the picture quality is so bad? What can be done to improve it? Later this year, I had planned on purchasing a stb in order to receive the hd/digital signals that the locals channels are supposed to be broadcasting. I want to watch these digital signals on my current 36" analog set. The main reason that I want to go through this process is because I cannot presently receive all of the local ota channels. Supposedly, when all of the locals become digital, they will be broadcasting from the same general direction, thus allowing for improved reception. That is my first goal, then I would like to move on to a hdtv. Is any of this an obtainable goal..........or is it a pipe dream.
