I looked at the listings for my zip code, and while I have 2 providers
in town, I see both duplicate listings of channels (the same station
listed on 2 different cable channel numbers) and unique channels from
both providers, but amazingly enough, there is little overlap between
the cable companies' channel numbers of the unencrypted content.  For my
town.  YMMV.  In fact, I'd be surprised if it didn't.

I wasn't aware that the HDHR would give you Firewire output, but if it
does, then it would seem obvious that you could receive OTA channels not
provided by the cable company via firewire.  OTOH, your STB should be
able to provide you with encrypted channels over firewire when you tune
the STB to it, should it not?  As to which is best, they are both
digital, are they not?  Shouldn't the quality be the same whether you
get it direct from your STB or you get it direct from your cable?
So you should base your decision on which is better by which will give
you more channels that you want.

disclaimer:  I do not use any firewire inputs with my MythTV setup as
yet.  So, I may be way off base here.

that would seem to be a better solution as it can provide firewire of
OTA channels if you choose to hook one antenna input to an antenna and
the other to your cable.
