There are good instructions on channel scanning here:

https://www.mythtv.org/wiki/Channel_Scanning

Make sure you turn on the "Full search for old channels" option.  Then
do "Scan of all existing transports".  That will scan all 5 of the
multiplexes on their existing frequencies.  If you do not have 5
multiplexes at present, or if a new one is ever added or the
frequencies ever get changed, then you need to use "Full scan" so that
all valid frequencies will be scanned to see if a multiplex is
transmitting on them.  A full scan takes a long time as there are
many, many unused frequencies to check to find the 5 that are actually
in use.
