thanks Mike. That's clears up a couple of issues. Is priority set by the 
field "Input Preference" in mythtv-setup? If so, maybe the text should 
change with the word "priority" in it.
How do you change the cardid? I'm sure it's in the archives someplace... 
I searched. I'll look more... I imagine it can only be changed in the dB.
