If it is one of the original HDHomeRun's, and you have not replaced
the power supply (at least once), it would surprise no one that it
is dying, and one of the symptoms is that one, or the other, tuner
may not be able to operate reliably (if can happen when both
need to work at the same time that one fails).  If you have a spare
power supply, it should be easy to swap it in and check.

FWIW, each generation of tuner has gotten better at reception,
so it is also possible that the quatro can handle certain reception
issues better than one of the original devices.  It is possible to
change the order of tuner selection such that the quatro would
be used before the original tuner if one wishes to use the quatro
in preference.

Note that the logs (and the recording details itself) should show
which tuner (inputname) was chosen for the recording, so you
should be able to determine which tuner was (attempted) to
be used.
