After a reboot, Tuner0 shows only static... To fix it:
/etc/init.d/mythtv-backend stop
mythtv-setup > input connections > tuner 0
clear "External channel change command" field
clear "Preset tuner to channel" field
set "Starting channel" to 3
/etc/init.d/mythtv-backend start
Now we have a picture but of course, cannot change channels. So, we set things back again:
/etc/init.d/mythtv-backend stop
mythtv-setup > input connections > tuner 0
set the "External channel change command" field to /usr/local/bin/changechannel hide box_type D10-100 setup_channel
set "Preset tuner to channel" field to 3
/etc/init.d/mythtv-backend start
Now everything works great (including changing channels)... until the next reboot. :-(
