Perhaps import/create the 6 muxes for the Winter Hill transmitter you
want to use in mythtv-setup, and then limit the channel scanning to
those muxes only - this would avoid the problem of the full spectrum
scan picking up channels/muxes being broadcast from the repeater. I'm
not sure if a tuned scan starting on one of the Winter Hill muxes
would completely avoid detection of the repeater muxes, but it's worth
The channel scanner in 0.22 saves previous scan information
(muxes/channels). This can be cleaned out by truncating the relevant
tables, but ISTR that you can clear this info out in the mythtv-setup
scanner GUI (away from machine at the moment, so cannot confirm this).

No. If your DVB-T tuners are all tuning to the same transmitter, you
just need to create the video source once and attach it to all of the
DVB-T inputs on the Input Connections screen.
