I have a new installation of NPVR, and am getting the same thing.
I was converting from WMCServer in Kodi, wanted to see how well NPVR would work.
Installed NPVR, set up the device (3 tuner Silicon dust HDHR), set up channels via Schedules Direct.
I get the guide, I select a channel, the HDHR LEDs show a tuner in use, then the LED goes out. After a few mins, I get the same msg as the OP.
I haven't even tried to set it up in Kodi yet.
