My guess is that it has something to do with your splitter. Have you 
taken note of which card is on the power pass output of the splitter? Is 
that the one that works, or is it the opposite, or is it random?

If your splitter isn't the type with a single power pass (or something 
fancier) then it's likely not suitable for satellite use. There's a 
possibility that some other kind of splitter may short the power to 
ground or something, which could kill the signal or trigger protection 
circuitry in the card.

It could also be that the signal isn't strong enough to feed both cards, 
although satellite cards should be of a high enough impedance that this 
isn't an issue...

If the power pass is all set up on the card that you want to control 
polarity (and I'm guessing you're only tuning horizontal on both cards 
anyway?) and that's not working, you might want to hunt for an option to 
turn LNB power supply off completely on the non-power-pass card. I 
haven't seen the option in myth, but I think one of the shell programs 
had it as an option so I guess some cards can do it...

That's all I can think of (bar linux device node issues etc)...
