[mythtv-users] is there a way to avoid tuning (recording) same multiplex on two different tuners?

I have zero experience with DVB, but is it possible to only put channels
from one multiplex on one turner and the other multiplex on the other
tuner?  Leave the Huappauge with both sets.  Give the dual tuners priority
so that it only goes to the hauppauge if it can't use one of the dual

If it works then you should be able to record three separate programs as
long as one of them is on a different multiplex to the others.

Like I said, no experience with DVB, so if it's a dumb suggestion chalk it
up to that.
