I agree that the 1800 should have only one channel, but that's not technically correct. 
In fact, SOMEWHERE in the settings, I've seen a list of FOUR tuners. 
This is because the 1800 can tune in one analog and one digital tuner (not two of either, but one of each!). 
As a result, I'd love to disable the analog tuner in the 1800, but I need to address the 1st, 2nd and 3rd things first, second and third.  

As for the number of capture cards, I have two configured.
I thought that was all I needed to configure and/or that was all I COULD configure (I've forgotten who told me what).  


> Also, how are you dealing with the inconsistent device names? Sometimes the kernel will "find" the 1800 first and make it video/adaptor 0 and give 1 & 2 to the 2250 while other times the 2250 will get 0 & 1 and the 1800 will be 2.


See settings that I've typed in below.

I have a very vague recollection of "7" being assigned to the 2550.  
However, I can't back that up right now, I recall that finding the information involved a "dmesg" command.

I don't know what you're talking about. 
What's a "pastebin" ?
