@thomaz - Thanks for your suggestion.
What should happen if there are multiple channels with the name name?
1) Skip that channel.
2) Use the first match found.
3) Analyse the ONID/TSID/SID of the connected services and try to match those.
What format should the export/import file be? Perhaps CSV or TSV so that it can also be manually edited by a spreadsheet if the user chooses.
This does not have to be built into TVH, it could be an external tool written in Python, Pearl, etc.
