My experience differs from your here. My cable provider recently changed 
over from us-cable-hrc to us-cable. One of my capture hosts was ofline for 
repairs, and when I started it up again, I forgot to change to the new set. 
I got, at least on *some* channels, a B&W picture -- bad but recognizable 
-- with lousy sound.  Other channels did bluescreen.

I recall looking at the actual frequency tables some time ago, and these 
two are fairly close for some parts of their ranges, probably close enough 
to give bad reception rather than none.

I may give this a try. (I don't know where to submit FAQ-page changes, 
which is why I didn't consider updating the Myth FAQ, and I'd simply 
forgotten that the HowTo ... for which I do know how to propose updates 
...also had something on this.) It probably won't be quite what you are 
suggesting, but perhaps close enough to help the many people who seem to 
run into this problem.
