Ummm. That might not have been completely DataDirect's fault...

DataDirect may have changed the way they were reporting information and
Myth has just made a change for it (
http://svn.mythtv.org/trac/ticket/1848 -- Daniel is still working on
getting the digital channel changes fixed).

It's only 20 channels. :) Do it this way.

Daniel has the start of a frontend-based lineup editor (which could be
the start of a frontend-based "Do you want this new channel"
functionality, ...). We still have a way to go, though, and it probably
doesn't make it high on developers' TODO lists because most developers
have their lineups already configured.

Please don't write the script (and add to the strain on DataDirect's
servers). It would be better to get a lineup editor in place as well as
new channel/changed channel/removed channel notifications, etc.
