V3Grab
From XMLTVDoc
When you have configured the program there are three ways to download listings:
To grab data simply click on Grab Listings in the GUI.
To automatically grab listings when the program is run use the /Grab command line parameter e.g. XmltvGUI /Grab. If you want to download listings without showing the program window run XmltvGUI /Grab /Silent
Alternatively simply run XmltvConsole
