I'm in the US, and am spoiled by the simplicity of Schedules Direct, so 
I can't say I'm familiar with the exact steps required for your 
situation, but I'm pretty certain it's possible.

Assuming your two cards are both receiving from the same service 
provider, I'm also pretty sure you should not setup two independent 
sources, as you will run into the problems you mentioned.

I have 2 cards also - one receives OTA broadcasts via antenna, and 
another receives analog video from a satellite settop box.  I have one 
source, but I have two lineups with Schedules Direct.  Most of the OTA 
channels are duplicated on the satellite lineup, and I just associate 
the OTA card with the OTA lineup for my region from Schedules Direct, 
and the Satellite lineup is linked to my old analog card.  It all just 
seems to work fine.

If you post who your satellite service provider is, I'm sure someone 
else on the list can help you out.
