[mythtvnz] MythTV 0.29 and HDHomeRun

[Brady, Mike]

I am running 2x HDHomeRun Connects on MythTV 0.29 without any problems. 
At least none that I am aware of. 

My Myth backend is KVM VM running Fedora 26.  The VM isn't new and has
been through multiple Fedora and MythTV upgrades.  Each HDHomeRun tuner
is configured with the maximum 5 encoders (so 20 total) and does
multiple recordings and livetv simultaneously no problem.

Added video source, connected them up in the 'Input Connections', scanned for channels. All ok at this point, so i start up MythFrontend and view LiveTV.  It works first time (yay).

> ok - so I've now gone into the backend MANY times and fiddled with the capture settings.  Deleted and reinstalled the capture cards.  Delete and reinstalled the video source, inputs, and channels.  updated software, rebooted machine.  Nothing works.  I'm at a loss...   No matter what I do, the error is always the same - UNKNOWN TUNER TYPE = 0XFFFFFFFF80000000.  Database repair via MythWeb shows no issues.  Note that that I can successfully SCAN for channels - this always works fine.  It is just live TV.  I'm not trying to use multi-rec at the moment, so number of virtual tuners is set to '1'.
