Tuners can be given priorities in MythTV Setup.  And you can do very
complex priority setups in:

Setup > Video > Recording Priorities > Custom Priority

There you can write SQL to adjust the priority of things.  I have
this:

MariaDB [mythconverg]> select * from powerpriority;
+----------------------------+-------------+---------------------------------------------------+
| priorityname               | recpriority | selectclause                                      |
+----------------------------+-------------+---------------------------------------------------+
| TVNZ multiplex             |          20 | channel.mplexid=2 and cardid in (1,2,3,4,5)       |
| Kordia multiplex           |          20 | channel.mplexid=4 and cardid in (6,7,8,9,10)      |
| Kordia 2 multiplex         |          20 | channel.mplexid=1 and cardid in (16,17,18,19,20)  |
| Kordia 3 (Maori) multiplex |          20 | channel.mplexid=21 and cardid in (21,22,23,24,25) |
| Discovery multiplex        |          20 | channel.mplexid=29 and cardid in (11,12,13,14,15) |
+----------------------------+-------------+---------------------------------------------------+
6 rows in set (0.000 sec)

which gives the use of specific tuners a priority boost of 20 for
specific multipexes.   It uses all the cardid values for the virtual
tuners on one physical tuner.  This means that each of the NZ
multiplexes normally records on the same tuner every time, and if a
tuner is giving problems, I can easily work out which one it is.
