   I had a major play in this area last month when my area had it's part of 
the UK digital switchover (all analogue turned off).

   I personally found the <ignore> options always did nothing (0.24-fixes). 
  At least, nothing I noticed!


   That said, I began to use a modified version of a script I found on the 
MythTV wiki that dumps my custom settings for DVB channels (like XMLTVID, 
comm-flagging, channel number, etc.) out of the SQL to a file, keyed on the 
OTA channel callsign.

   Then I delete all DVB channels, rescan [existing transports], and 
re-import the custom settings.  If I think there's more than one channel's 
worth of changes, that's what I'll do.

   You then just have to re-fetch guide data, as I think they're held by 
[mostly arbitrary] chanid.  *That* said, using this method gives me ptryy 
much the same chanids for each channel as before, so last time I did it the 
guide data remained valid.

   Scripts here:

   You'll see the fields I care about being stored.


   (I've since modified my local copy to renumber any new channels out of 
the way (+10000) of my satellite box, which effectively lays claim to 
100-999.  Our interesting DVB is mostly 1-99 at the moment.)
