That is correct, but the poster just mentioned that there were 5 channels moving to digital. She didn't mention if they were local channels or basic networks like Travel, GSN, etc. Comcast has been moving those types of channels to digital, and sometimes encrypting them, in which case a QAM tuner isn't going to do you any good (unless you get a CableCard, but there's no way I'm going to recommend that to a technical novice).

You're also correct that the set-top boxes sold in stores are not QAM tuners, they are ATSC tuners. ATSC tuners can only receive signals over the air. As far as I know, there are no set-top QAM tuners available for sale, but most modern digital TV sets are equipped to tune in QAM channels on cable. Since some are not QAM-tuner equipped, this is an important feature that you should look for when purchasing a digital TV, if you are a cable subscriber.
Agreed that getting a QAM-equipped TV is best, but I'll note there are some DVD recorders with QAM tuners that could serve as a substitute if you're lacking a QAM tuner.

Pretty much, yeah. If you have a newer HDTV, with a QAM tuner, you could just scan the channels to see if they come up. If they don't, or if you have an older TV, you're stuck with the cable box. The DTV converter boxes in stores won't help you here.

I bought the converter box and scanned all the channels, I get all the local stations here in sacramento except 10. I have not been able to watch my extreme makeover home edition for 3 weeks now. Will I get 10 after June 12th. I used to have directv but in the complex I live in we were charged for 2 bills,1 bill for equipment rental and the other for the service. Stupid huh.

One of them was airing ads that their digital signal would go to their VHF channel (can't remember if it is 7 or 9) on 6/12. I'm assuming that I'll have to re-scan the channels then. Also, right before the 2/17 deadline, channel 26 suddenly came up good on digital but after the delay it has been gone. I hope they increase their signal.

Some signals will go up after tomorrow so it would be wise for everybody to rescan Monday night. Some digital stations were held at half power to avoid interference with existing analog stations on the same frequency. Those analog stations have to vacate the frequency at 2PM EDT tomorrow.
