If your cable modem is providing DHCP services to your network and you haven't power cycled your HDHR since the cable modem was restarted, then power cycling the HDHR will allow it to renew its DHCP lease with the cable modem, and might help mythbackend find the HDHR. I would first power cycle the HDHR, then restart the mythtv-backend service.
