First of all, open each tuner in mythtv-setup  and set the number of
virtual tuners to 2 or 3... this way if you record 2 subchannels of the
same channel at the same time, you will only use one physical tuner.  On
your TV you would see this as 47-1, 47-2, 47-3 for example.

I guess recording/livetv priority was one of the new features in 0.25.  In
0.24, you can set each tuner's priority and in the settings menu on the
frontend you will find settings talking about livetv and scheduling (been a
while)... but one of those settings will make live tv use the lowest
priority tuner available; which with that many tuners, will likely not be
used by the scheduler if you set the priorities in the section you
described above.

I HIGHLY recommend upgrading to 0.25 or even 0.26... there are issues, but
I am much happier with 0.25.
