I'm using the HDHR on a digital cable system, and I'm just wanting the
local channels (i'll take whatever else I can find though) for when
the big networks run shows against each other in Prime Time.

I'm confused about how to use the channel scanner to add channels when
it says they in conflict.

It seems that my whole backend and frontend have become unstable now -
I need to re-read Michael's comments on how channels are tracked in
the database and what I need to know to keep it all straight for the

When adding channels, when I was asked to pick a channel number or
even have one suggested, it was always in conflict. I even tried
'crazy' channel numbers so that they couldn't be in conflict and yet
they were. I'm left to discern that the conflict isn't related to the
channel number, yet that seems to be the only identifier I'm asked to
make input on by the channel scanner.
