That's probably the easiest way -- you could also mess around with the 
settings using test_ioctl with one channel, then transfer those to the 
database for all the channel entries at once with those values.  The db 
stores all the picture controls as values from 0 - 65535, so you'd have to 
translate the ivtv's ranges into that range (ie, what mythtv does internally) 
to stick em in the db.   Just be something like:

    update channel set brightness=32768;

from the mysql command line client, assuming you only have the one pvr card 
and you want to change all the brightness settings for all channels.  I'll 
see about adding a 'Set all channels like this' button once I get around to 
making a better OSD menu for all these controls.
