My question was a bit rhetorical. I was not so much saying what fields
would need to be changed as saying why can't Myth stations/channels be
edited by changing the relevant values in the interface that is already
there. We know from comments that when there is a frequency repack that SD
gets tons of questions from MythTV users. Other programs must handle a
repack in a more straightforward way.

That said, your script and the example you give in your email look like a
great step forward in making this a painless process.  I look forward to
trying it out when the time comes.

As a final check, is there anything about what I am running that might give
me trouble in using your script?  Best I can tell from the Ubuntu
documentation the perl binding was part of that build. I am, however, not
at all sure of that.

Mythbuntu 14.04.1 LTS and MythTV fixes/0.28
