The HVR-1950 functionally is a single tuner that happens to have both a 
digital and analog receiver.  But it's a single tuner.  Only one side 
can be used at a time.  Probably when the mythtv back end opened the 
digital side it caused the analog side to be locked out.  It's one or 
the other, not both at the same time.  (And by "same" I mean if anything 
tries to acquire a lock, i.e. "azap", on the digital side then the 
digital side is open and active and thus the analog side is not 
available.)

All is not lost however.  There should be a means in MythTV to tell it 
that the two devices are related to one another.  That should allow the 
back end to correctly sort things out.

This sort of behavior is not unique to the pvrusb2 driver; it will 
happen with any hardware used by MythTV where there are both analog and 
digital sides.
