No, you have missed the point I am trying to make - it is not the same
problem at all.  With two inputs and no onboard splitter, you would
use an external splitter with the correct number of outputs for all
your devices, say two for the HVR-2200 and one for the TV, and all
three get the same signal level, a bit less than one third of the
input signal.  If you have an HVR-2200 with one input and an onboard
splitter, you use a two way external splitter and the TV gets just
under half the aerial's output signal level. But the HVR-2200 also
gets just under half the aerial's signal level at its input, which it
then splits so each HVR-2200 tuner winds up with well less than one
quarter of the aerial's output signal level, versus the TV with just
under half the aerial's signal level.  The problem is that a dual
tuner device has an internal splitter that you are forced to use in
series with any external splitter - so any tuner on a dual or multi-
tuner device will always get much less signal than your single tuners.
