Eureka! We have lift off, all systems are GO!! Thank you gentlemen, this old nob is grateful. I usually hibernate the PC when not in use to keep everything in place, maybe a reboot when thing are not right is the answer. Thanks again!
The problem was caused by you unticking that checkbox sometime in the past, and your HDHomeRun's have probably changed IP addresses or something since then.
The reboot was just to make that setting take affect again after you ticked it.
Part of the reason for this is what I consider a logic issue in NextPVR. If a configured HDHR is not detected at boot time even if it is days before, the HDHR won't even try and record. It should not be automatically disabled until it truly fails. If it fails after boot it is not disabled.
