I'm going to have to spend a little time with these, as they are long 
with many commented lines.  But already I have found that there is a 
/lib/dev-state/v4l/video0 and that could be where the unwanted 
settings are being picked up.  I'll do some more work on this.  Just 
changing them there hasn't been enough.  I'll come back when I've 
read a bit more.
