No. No, no. Absolutely not. Wrong, wrong, wrong ;-) No one in the
future should ever do this.

When one channel changes it's channel number:

1. Do not shutdown the backend
2. Do not run mythtv-setup
3. Do not delete channel settings
4. Certainly do not much with the video sources
5. Don/t change any source name and if you're getting authoritative
data directly from a media service, don't refer to it as a third
party web page scraper.
6. Don't change you input connections

Generally if a new channel is added it should show up automatically.
In this case where the channel number changes, all should have been
well if you ran mythfilldatabase with this option:

   When using data direct, ask mythfilldatabase to
   overwrite channel names, frequencies, etc. with the
   values available from the data source. This will
   override custom channel names, which is why it is
   off by default.

If some channels change or are dropped, there can be old entries
left behind. The channels you no longer can be removed by following
the HOWTO:


In any case, don't blow away your channel table and sources and
source names and input connections every time there is a callsign
change or whatever, okay =).
