No!
You will need HD Cable Box to get HD Cable and then only certain channels are going to be HD. Not all channels, in fact most channels are still not in HD.
The HD Tuner (ATSC/DTV/HDTV Tuner) that is inside your TV is ONLY for OTA (OFF/OVER-THE-AIR). The "Locals", stuff like ABC, NBC, FOX, PBS, CBS, ... To get these, just hook up an antenna from Rat Shack. The farther you are the better the antenna you need. My "Locals" are 50+ miles away, we have an antenna on the roof and they come in crystal clear.
If you want to get HD Cable channels you will need to tell your cable provider you want HD. You will need a special HD box from them.
