hd broadcast general questions

[joez]

I have been so involved in choosing an HDTV that I did not learn about actual HD stations and how to receive them.

Can anyone help a newbie, please.

What are my choices. Will a built in tuner be a waste of money?

What is in the future. Will a roof top ever compete with digital cable or satilite.

sorry for all the questions... does anyone have a general overview.

THX!
