Tvheadend does not come with any xmltv grabber. You need to install the grabbers your self.
Tvheadend is looking at the following directories to see if it can find any xmltv grabber:
> Where does Tvheadend scan for XMLTV grabbers?
> /bin
> /usr/bin
> /usr/local/bin
> /usr/bin/perlbin/vendor
> All directories specified in the $PATH environment variable
