The MythTV software handles HDHRs the same as any other tuner for
recording or live TV.  The only thing that is different is the actual
driver code that interfaces to the tuner via the network.  After that,
the code used is the same.

How old are the HDHRs?  The usual problem with them is that their
power supplies fail with age and need to be replaced.  There are many
possible symptoms from that sort of problem, so the easiest way to
know if that is the problem is simply to have a spare power supply and
swap it for the suspect one.  It is best to get a higher quality power
supply for a replacement as the ones you get from the manufacturer
will themselves fail in time also.  There should be a panel on the
power supply (on the bottom?) that gives the voltage and current
ratings and tells you the polarity of the plug.  Any replacement
should be the same voltage and polarity and the same or slightly
higher current rating.  If you hunt around in your discarded
electronics bin, you may find you will already have a power supply
that will do the job.  Some replacement power supplies come with
switchable voltages and a set of different plugs with swappable
polarity.  Having a power supply like that allows you to swap it into
a large range of different devices at need, so I try to always have
one of that variety available as a temporary spare.
