Ok just bought a new 32" sony LCD tv 720p. I had a regular old 27" tv before and basic cable from my local cable provider wich is channels 2-78. Now I am getting channels like 63.3 and 96.7 and so on. These are all channels that are offered through my cable providers digital cable service where they send you a digital box and it is more expensive. For example STAR tv is channel 138 through there digital service but I get that channel on 93.7 for free. How come I am getting these channels for free with this new tv?
