Updating Channel Lineup
Every now and then a cable company completely rearranges their lineup. The claim to do this in order to make things better, but it often seems that it's turns out being nothing but one big pain in the butt. Not only do you have to relearn where all your favorite channels are, but you have to fix MythTV as well! If you're a victim of this, hopefully this little HOWTO will help. It's most likely not complete as it's being written by a relative novice who mostly sits on the sideline but was a victim of a recent cable lineup reorginization.
Always Back Up
As always, whenever you're going to do anything that may be invasive to your MythTV setup, make sure you backup your database.
Let MythTV do the work
If your data source (zap2it in my case) has already picked up the new lineup, the normal update script, mythfilldatabase, seems to do this job really well. However, it needs to be run with a special switch to make it happen.
$ mythfilldatabase --do_channel_updates
In my expirience, this updating upcoming recordings, channel icons, etc. It all seemed to work.
