This might be as a result of the new "Schedule as a group" option.  If
that is set, as I understand it, it overrides the setting for the
number of multirec tuners and the system will create virtual tuners as
required.  I have never used that option, but I understand it is on by
default in new installs.  You find it in mythtv-setup > Input
