I've just noticed that a helpful reply about this came off-list.
'Delete all video sources' does it, but also deletes all Transports and
Channels. Scanning didn't work for me with Transports defined in an
empty list by the Editor, so starting a 'Full scan' was needed
initially. Inter-Transport links can be exploited later, and can help
if you receive from more than one transmitter.
This shows what is going on. Direct manipulation of the DB is discouraged.
