One thought that comes to mind ...
If you only have 3 muxes, then you could dedicate one tuner to each
mux. I'm not sure of the steps required to do this (I only have one
tuner, and 5 SD muxes) but I think you'd configure an input on tuner
1 and only create channels that are on mux 1; then you'd create tuner
2 and only add channels from mux 2 to it, and ditto for mux 3.
That way, unless you exceed the number of virtual tuners, the
scheduler will always pick one of those three tuners - ie the lowest
number/highest priority tuner for any channel will be one of these
three tuners, and one of them will always be tuned (or available to
be tuned) to the mux required.
Then you'd add your fourth tuner, add all the channels to it, and it
should always be available for live-TV.
