[mythtv-users] strange mythbackend output

[jimbob]

after i run setup and configure everything i run mythfilldatabase, and
get:

Grabbing XMLTV data using Adjusting program database end times...
0 replacements made.

which is the first wierd thing.  i thought this was supposed to download
all programs.  after that when i run mythbackend i get:

Starting up as the master server.
One of your capturecard entries does not have a hostname.
  Please run setup and confirm all of the capture cards.

and i dont know what config file to change, or what to do. please help.
thanks.
