[mythtv-users] Adding PVR-250 to already existing PVR-350 system

[Michael Starks]

Thanks for all of the replies.  As is often the case, I messed with it 
until I got it working and I'm not quite sure of the sequence of events 
that actually fixed it.  It probably had at least something to do with 
the cable not being plugged into the second tuner. :)  I figured I would 
see static when I was testing but maybe the driver doesn't initialize 
properly without a signal.
