I am considering taking the HDTV plunge, from what i understand the only HDTV signals you can recieve are from either local OTA stations or the two on Direct TV. I live in Buford-Cumming area and I am concerned that I cannot get the ATL OTA stations, I have tried the atenna.org site and it said I could only get PBS and ch46. Does anybody have any experiance in the North Atl area, or know where to go to find out about signal strenght?, Thanx Terry Brady
