[mythtv-users] Nova TD Stick USB dual tuner, cannot tune same channel with both tuners

[Alex Fazzari]

Added a nova t stick (single tuner) yesterday and it's appeared to
make the problem worse on the DT dual tuner.  With the single stick in
I can't activate both tuners in myth as they both become unusable.
Choosing to use either tuner individually and not loading the other
works though - I've decided to just use this as a single tuner for now
and get myself a HVR2200 this weekend.
