Yes, I definitely have the right card selected (and I have tried all the 
drop-down options for the default input box).  The problem is obviously 
mythtv is setting (via it's ivtv interface) the default output for the 
card when initiating a recording.  I must not have this correctly set in 
mythtv which leads to it overriding my setting it from v4l2-ctl.

So my question still stands, how do I tell mythtv which output to set on 
the PVR-350 when it initiates a recording ?
