If this is your first network tuner, you may not have done the fix for
getting mythbackend to start up only after the network is actually
available.  So every time you reboot, mythbackend will not see the
network tuner as it starts when only localhost is up.  If it is unable
to test a tuner at startup, it marks it as bad and does not use it. To
test if this is your problem, just restart mythbackend, and as the
network is up now, it will see the network tuners and everything will
work unitl the next reboot.

If you need that fix, see my post on the recent "Need mythtv-backend
startup advice" thread.
