I believe the problem, James, is this:

You may have two different lineups (which Myth calls Video Sources --
in my case "Bright House Cable - North Pinellas") which *carry the same

Since they're from different Video Sources, Myth won't assume they're
the same channel.

I *think* this is the problem the original poster is having, from his
description, and my understanding of how Myth numbers channels
internally... but I'm sure if I'm wrong, Bruce will correct me.  :-)

The problem is that it *isn't* channel "122".  It's channel "1122".
And the one on that other tuner might be "2122".  See?

On a related topic concerning LiveTV, we seem to have discovered that
if you hit LiveRecord while watching, and there's another available
tuner card, Myth will use *that* to record, instead of the tuner you're
on.  Since how channel change commands are responded to depends on
whether you're watching the card that's recording, and they're the only
*convenient* way to see if a manual recording has actually started,
this is a bit confusing until you figure it out.
