@finbarr - Maghera is already in the standard terrestrial.xml file, although it's at the very end! See below. ABM seems to have issues with HD bouquets in Freeviw, but should be fine with SD from Maghera. ABM doesn't work at all with Saorview, though, due to non-standard settings within the NIT.

Code:
<terrestrial name="Maghera (Ireland) (Europe DVB-T)" flags="5">
		<transponder centre_frequency="690000000" bandwidth="0" constellation="3" guard_interval="4" transmission_mode="2" hierarchy_information="4" inversion="2" />
		<transponder centre_frequency="746000000" bandwidth="0" constellation="3" guard_interval="4" transmission_mode="2" hierarchy_information="4" inversion="2" />
	</terrestrial>
