Yeah something like that.
It's not straight forward since that field in the database is a set so we can't just poke new values in there without updating the database schema first. Need to be careful not to change the order of the values so any new ones would need to be appended to the end of the set.
There's a number of problems though which is why I keep putting looking at it of like updating the DB schema in master is fine. Updating it in 0.28-fixes could be a problem
Filling that field during a scan is no problem but how do we update existing channels in the DB. It will probably involve a lengthy DB update to check each IPTV channel and update the field in the DB as appropriate.
