That's normal behaviour, and rescan after a lineup change is a routine  
operation now.

The problem here is that on MythTV, a rescan didn't work.

Deleting the channel, and doing a rescan didn't work.

Deleting all the channels, and doing a rescan didn't work.

The only way to get 'Virgin 1' and 'Virgin +1' in the right channels  
was to delete all channels, force a database sync by running  
mythfilldatabase from the command line, and then do a rescan.

The obvious fix is to put in an option to 'delete all channels and  
rescan', and do a database sync when doing a rescan,
