Another computer on the bedroom circuit, that's about a 100-200 watts tops if 
it were on, which I don't think it was.  I did notice the bedroom circuit is 
right above/below the living room circuit in the breaker box, so I attributed 
it to the breaker location within the box, and the fact the PVRUSB2 29061 was 
no longer working.  On other circuits, there's an electric kitchen range which 
I did operate just as the other two circuits tripped.  Also have a septic pump 
and water pump which *might* have been operating at the time, again separate 
circuits/breakers.

Not too worried about it now, as I'm pretty sure it was the old PVRUSB2 29061 
power supply.  Nothing else could really explain such a scenario, unless the 
grid took a spike.  Also well grounded here.  One exterior perimeter ground, 
and one on the basement ground water well pipe.  Also another separate ground 
rod for the antennas. ;-)

Shrugs.  Stuff happens as they say.
