Please avoid top posting (put your reply's below the quoted content).

Anyway, in mythtv-setup, when you are mapping sources to tuners, there is
an option to set the recording priority and the livetv priority.  I'm
pretty sure it was there in 0.24?

Essentially when entering livetv it will choose the tuner with the lowest
livetv priority; if you set the livetv priority to 0 that tuner will not be
available when entering livetv.  The same goes for the recording priority.

Are you running 3 HDHR Prime's with cable cards, or are you using QAM, or
ATSC?  I only ask because if you have 6 physical tuners, you could have 2
or 3 times that with virtual tuners (unless they are Prime's with CC's),
that many tuners may influence the way I'd set the priorities, so I won't
make any recommendations.
