It sure sounds like a lot of people aren't scanning for the digital channels to me.

The new tv's need to have the digital channels entered into them to work properly, you may have to scan for existing channels several times in order to get them to work.

All of the descriptions I'm reading here are very reminiscent of what my new HD digital tv was doing before I scanned for the channels. After reading the manual and actually doing the scan, like magic I now get more channels than I even want.
