I have the same issues. My LiveTV/DVR says I have no DVR Configured. When I go into the DVR settings it says I don’t have any tuners. When I try to add tuners it doesn’t see them. When I try to add manually it only connects to one, but never completes the tuner add functionality. My Live TV/DVR is dead in the water. I can see the HDHomeRun tuners using the HDHomeRun app on the same machine. I am running Windows 10.
