If yes it is possible to hook into set_voltage and use this to disable LNB voltage for power saving. > This is what happened when I started vdr. > > Vertical gave a Volt reading between 13.9 and 14.1, Horizontal Gave > 19.4 ~ 19.5.

The voltage after stopping vdr is no surprise with zl10313, look into the code at mt312.c line 425, The value it writes for no voltage is the same as for vertical voltage.
