Does it make sense to have a post code?  That, is, would it be possible to
intelligently guess which providers are available given a geographic
location, if you had that information?  If not, don't bother with it;
there's no need to support all of tv_grab_na's options unless they make

Or rather, first select tv_grab_uk, then enter their postcode and choose a

Yes...what about the other providers?  Are you planning to include the
channel list in the grabber?

Yes, this will probably be a generic channel selector for all grabbers
(maybe saving the settings differently, depending on how that falls out).

I don't think this level of granularity is necessary, myself; these things
tend to change with time anyway.  Users can easily enough select the
channels that they actually receive.

Right now, the approach is to add all channels, and the user can change them
by hand or using tv_grab_XX --configure.  This seems sufficient until a
graphical channel editor is added.

Currently, I believe channels are strictly per-videosource, i.e., any two
channels on two different sources are always considered to be different.
This could presumably be enhanced in the future to recognize if two channels
are actually identical, if someone wants to do it.
