This may be the problem - your database has two tuners.  I completely
missed that both of them are pointing to /dev/dvb/adapter0/frontend0!
That is completely invalid, and I do not know how MythTV allowed that
to happen.  As well, if mythtv-setup is only showing one video source,
and the database has two, then it must be rather screwed up.
Fortunately mythtv-setup has a option for this situation - delete all
the video sources, tuners, channels and so on and start again from the
beginning.  There is a special menu option that should do that.  Go to
the Video sources menu and use the (Delete all video sources) option.
When you use that it triggers the use of special code that cleans up
the entire tuner database allowing you to start again from the
beginning with those parts of the database completely empty.  So any
invalid data that is not currently appearing in the mythtv-setup
options (and consequently can not be deleted) *will* be deleted by
that command.

When you configure things again, just set up one video source with EIT
on, and one tuner and one input connection for that tuner.  Set the
Max recordings for the input connection to 3.  Then scan for channels.

Yes, I am a night owl.  I am often up very late - but sleep in during
the morning.  New Zealand is UTC+13 at present - daylight saving of 1
hour finishes on 1st April, after which we are back to UTC+12.
