It would be nice if that were true, but it is not. You will have to  
do another channel scan because the multiplex numbers are tied to a  
specific input card. In my case I started with 18 multiplexes on a  
single card and added a second pcHDTV to get 36 multiplexes -  
multiplex 1 is the same as 19 except for the source card, 2 is to 20,
