I'm using a similar arrangement, Mythbuntu 14.04 (0.27.5) with two HDHR
Primes. I have the tunners assigned according to this chart:
HDHR Tuner Assignments
Tuner Encoder Sched Priority Live Priority
131F6472-0 1 1 6
131F6472-1 3 3 4
131F6472-2 5 5 2
131F9021-0 7 2 5
131F9021-1 9 4 3
131F9021-2 11 6 1
I also specified one recorder per tuner in the backend setup.
It has worked fine and I haven't missed a recording even with 6
recordings running at the same time.
