We have no power at home at the moment (and may not for sometime,
hopefully not days!) so I can't check things.  From memory, for the
internal and USB ethernet adapters the UDEV rules are pretty similar to
mine and I don't believe were the problem.  The USB adapter recognises as
eth1 fine.  When plugging network cable into it and switch/router it comes
up with IP address fine (viewable and changeable in GUI and via ifconfig),
plugging network cable into it and hdhomerun it doesn't work (I think
IFCONFIG showed UP on eth1 status but no IP address details and it isn't
changeable/settable in the gui)

Yes, will certainly fix the IP address via DHCP if it stays on the main
LAN regardless of whether or not I get auto discovery working or not (also
only the one hdhomerun at present so it's easy to know what's what).  The
issue with accessing via IP instead of device ID that I read about in
passing was something like a lock up or failure when accessing tuner via
IP and another tuner on the device was closed.  If others here have MythTV
backend setup configured with the hdhomerun's IP address and not device ID
it sounds like it's not going to be a problem.
