Thanks for the replies guys.
What I was hoping was to get away from the lots of masters / lots of
slaves (with lots of tuners) problem.
I was hoping that the "Set Top boxes" could be MythTV boxes with both a
frontend & a back-end together and then in the room where all the TV
cabling comes in I'd just have one or more PCs with a tuner card for
each channel (actually I was hoping I could be smarter with a multiple
channels from a DVB-S / DVB-C card with many channels from the one tuned
transponder so even less than one tuner per channel).
This way I would only have 1 tuner per channel streaming out to all
MythTV front/back ends in each room with each of them doing their thing.
It would be great to be able to offer the live TV pausing features, etc
