So if I create listing, for each type of tuner, then you're saying I'll
get a smart, integrated channel guide?  (between SD and HD?)

What happens when I add Comcast HD tuners that will overlap a few channels
with the HDHRs?  Wouldn't I end up with duplicate listings for something
like the local NBC affiliate?  How does that get addressed?
