Delete ones that don't work using your logs as clue.
Use the option scan existing transports.
Not that likely the multiplex transports have been (frequency)
restacked.
Less likely they have all been restacked.

Use the option to follow any new transports signalled in existing.

The external scan tool w-scan is faster.
The logged output from MythTV scanner is very informative.
