I believe it is because mythtv-setup takes a numerical ip address and
if your ip address changes you will not be able to connect. I have
been using DHCP for years but my dhcp server never gives my machines
different ip addresses (as long as I keep the router always powered)
so all is well. I have a $100 PCM 1000VA ups that powers this as well
as my master backend.
