Yes, that's it, it would be a kind of bit-mask.  It'd be a way of
expressing this kind of info, without having to have a column per
source or something, which would be unworkable.  I do apprechiate that
doing operations on this kind of bit-mask number could be quite
difficult compared to the simple = operaton.

Well, for a GUI setup, it need not be too complicated.  You could just
have it as a grid, with a list of channels down the side, and sources
along the top, and the user could just tick boxes to show which
channels each source had.  Also, I don't see why mythfilldatabase
should be different, since it'll just grab listings for ALL channels
regardless of which sources they're available to.

And you shouldn't need to specify a "favourite" card for each channel. 
It could still treat the first card as favourite overall, but if a
channel isn't available on that card, it'll just drop to the next card
and so on.

As I said before, I do feel guilty for posting a "what I would like
is...." without being able to offer actual code to back it up.  I do
think Myth is already totally awesome, and I wish I could contribute. 
But, from reading other emails in the archives, I'm sure I'm not the
only person with this kind of set-up.

Cheers again,

--Dave
