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.
Please. I know that a rescan is needed. I understand that the bandplan shifted channels and frequencies to and from VHF-lo and VHF-hi and UHF bands. I understand that the signals have different propagation patterns. I also understand that VHF-lo is a bad band for the ATSC signal, and that they also cut back the ERP of many transmitters from 100KW and more to under 50KW because they expected to be able to save power costs.
I also know what a decent antenna looks and works like - I've built more than a few myself.
This was nothing less than bad engineering, bad politics and bad economics for everyone who isn't in the business of selling content and hardware.
Imagine we did the same thing for telephone service. Would it be acceptable for 5% of the people who don't have a digital telephone to lose their phone service after a cutover?
