Channel table
From MythTV Official Wiki
Each row in this table describes one tunable channel, where a channel is a frequency (and possibly a subchannel id for satellite and digital cable) -- if you get CNN from two Video Sources, it will appear twice in this table (though, as long as the callsigns are the same, ScheduledRecordings will be moved from one tuner to another, priorities permitting).
