[mythtvnz] PVR-500 Tuner Usage

[Mike]

Ok, I seemed to have buggered something up recently (although I can't
remember what, if anything I did).

I have a pvr-500 in my mythbox, and for some reason if I have two
programs back to back it will only use the 1st tuner, the 2nd always
sits idle.

What do I need to change to make it pick the 2nd tuner?

I only use the pvr-500 for recording prime, all my other channels are
covered by two skystar II dvb-s cards.

I am running 0.20.2

TIA

Mike
