I have subscribed and setup DVR. DVR does not, however, find any of my tuners. I have a HDHomeRun Extend v2. Both Apple TVs find the HDHomeRun fine. DVR is installed on a Synology. I have restarted the DVR service on the Synology, and I have also rebooted the HDHomeRun.
I read the thread referenced VirtualBox network settings (DVR does not find my tuners (VirtualBox network settings)), but that doesn’t seem to apply to my issue.
