> Yes, I got all that.  I was apparently a little confused with the "change virtual tuners from 2 to 4 as you connect them".  So you're saying I could have simply changed Max Recordings to 4 on each capture card as I added it? After defining all my capture cards with 4 tuners, THEN gone in and connected them in the order I want them used for recording? 	

No.  You add your tuner cards with however many virtual tuners for 
simultaneous recording you want, and go all the way through all normal 
configuration and set up in mythtv-setup for them.  Then you go back and 
add one additional virtual tuner each.  I only said to use four, because 
you are limited to five.  You could use two virtual tuners, and then 
afterwards add a third on each for livetv.  You could use three virtual 
tuners, and then afterwards add a fourth on each for livetv.
