Tvheadend

Hi everybody,

I've got a Synology NAS DS412+.
On this I have installed TVheadend 4.2.18-4 (through http://packages.synocommunity.com).
Everything works well so far, but what I don't get is EPG with an xml file.
TVheadend has been installed on /volume1/@appstore/tvheadend/ and I get (or see) only the EPG Grabber (and it shows "disabled").

What I would like to do is download an xml file and integrate it into TVheadend ... in order to have updated EPG dates always.

I would be glad about any support or ideas.
