k thanks for the help guys. lets see what else i have questions about. i'm lookin at something like this...
http://www.sonystyle.ca/commerce/ser...th=32050n45260, and it sais that it has a "Built-In ATSC Tuner". so that would be the over the air signal you're talking about would it not? that's all i'd need to watch hdtv, as well as an HDTV (obviously). couple more quesiotns, if you have a regular tv and an hdtv both watching the same show, will the hdtv be in better quality than non hdtv or does having an hdtv only make a difference for shows in high definition? and third, do you get more channels if you have an hd signal receiver? thanks again
