Thnks to folks like you those who are ignorant have a chance to understand. But mention that NTCS was adopted in the 1930's ? or so by a group of bald old farts who were dead well before TV was available! Due to their actions we all pay the price of Fuzzy, out of focus Tv!! So when we see what they offer on a big screen, no wonder HD is a miracle!! I never voted for G Bush!!
