[mythtvnz] DVB-T signal strength

[Dr. David J. Knowles]

I believe that Nova T cards have signal strength issues if the amplifier
is not used.

    * *Very Important* Turn on the onboard amplifier or you will get
      very poor signal strength. It is possible that this will cause you
      to receive no signal at all due to the amplification of signal
      noise regardless of signal quality.

sudo gedit /etc/modprobe.d/options
/Add:/ options dvb-usb-dib0700 force_lna_activation=1
