This is because you can't do a mythfilldatabase without any channels.

However, you should be able to get channels by using the Fetch channels 
from listings provider option in Connect Inputs in mythtv-setup.  If 
that doesn't work, you may need to do:

mythfilldatabase --only-update-channels --do-not-filter-new-channels

to get the channels into the connected Video Source, then use:

mythfilldatabase --dd-grab-all

to get the data.  See, also,

and

for details about --dd-grab-all
