Ok, then try it the other way round. This is explained in the Myth 
documentation IIRC. You set up a digital cable lineup on Schedules 
Direct for the  channels you want to watch, first, then, when setting up 
the Input,  you select 'Retrieve lineup from Schedules Direct'. I've 
never used that method but for a long time, it was the method of choice.
