It actually doesn't work quite this way on my system (Mythbuntu 
8.10--think this is Myth 0.21). I've assigned the better card priority 1 
and left the lesser card's priority at 0. Having done this, I find that 
when the "Avoid conflicts between live TV and scheduled shows" option 
(under Utilities/Setup > Setup > TV Settings > General) option is ticked, 
my machine shows Live TV using the better card. I should mention that I 
have not tried this while the machine is doing a scheduled recording. When 
I untick that option, on the other hand, my machine _does_ show live TV 
using the lesser card.

So, what's up with that? Does this mean that, when I have the option 
ticked, my machine will only show live TV using the worse card if there's 
a scheduled recording underway? I wouldn't mind that scenario so long as I 
could be assured that the machine would _always_ record using the better 
card. My experimentation to this point seems to indicate that the way to 
get the machine to show live TV using the lesser card is to untick the 
"Avoid conflicts between live TV and scheduled shows" option. But I have 
yet to see what the machine will do when a scheduled recording is taking 
place with that option unticked.
