Ok, good suggestion,
The Shield and the HDHomeRun are all connected to the same router and Shield is hard wired to the router. I do have an 8 port switch which may be the culprit? I will check the wiring. Wow, I did the wiring exercise to ensure an always stable connection.
You answered this before but to be clear with tuner sharing off it does not matter whether I use Channels App or Channels DVR app, correct?
