I was considering getting one of these coupon eligible converter boxes in case the cable goes out. If the cable is out I can't watch any TV unless I hookup the antenna. So far, I have not been affected by the analog to digital switch that happened earlier this year. It sounds as if you're saying that even though I have digital cable, that one day I'll need a special converter box to watch antenna/broadcast channels with cable tv. I'm beyond confused about that. I thought Comcast provided their converter boxes so people could watch their cable channels which include regular antenna channels.
Just to clear things up. Comcast is going all digital on their systems so eventually you will need one of THEIR converter boxes to get cable on all your TVs. Now this has nothing to do with the DTV switch that just happened It's Comcast's own thing. Getting rid of analog frees up bandwidth for more HD channels.
Now as far as your old TV if they were made before March 2007 they probably don't have built in digital tuners so if you want to watch OTA TV then you'll need a converter box designed for ATSC signals. Cable boxes are designed for QAM signals. Good luck finding a digital converter box for OTA anymore. I don't see them for sale anywhere.

Is there any point in me getting a DTA converter box? I orginally wanted to get one in case the cable went out for a long period of time. But if one of the tvs is SDTV and the new tv will also be SDTV, do I really need a converter box? I don't have or plan on getting HDTV anytime soon unless that's the way things will be heading within the next three to five years.
I hate to tell you no one sells SDTVs anymore. Not new anyways. Any new TV you get will be HDTV. It will have have a digital tuner in it so you won't have to worry about needing a OTA converter box for that TV.

As far as the HD thing goes, I didn't realize until after my first post that so any new tvs are HDTVs. So, just ignore what I said about HDTV.
Just to be clear a SDTVs can be digital it's just they aren't made anymore. In fact there were SDTVs made with digital tuners in them. Just because a signal is digital doesn't mean it's HD. Many stations broadcasting OTA have subchannels and those subchannels are often in standard def, as in 480i. That's not HD. Most of the channels Comcast has in their digital tier are not HD. Not sure why people get confused that all digital signals are HD.
