Consider using a 4-tuner HDHomeRun box. It is not really important which of
the four tuners are used so a string like "HC" (short for HDHomerun Cable)
could then be used for all four input connections.
So I suggest doing it the same as in mythtv-setup; generate a default that
is unique, e.g. "Input 12", but leave the decision to the user.
