Uh, what? No card has a tuner that changes the channels on a cable box. That's 
done via firewire, serial or something like an IRBlaster. The on-board tuners 
can only change their own channels, and that's the same for every card... 
Both tuners can be used simultaneously if you're piping them a signal 
straight from your cable provider or OTA, with no intermediate device (like a 
cable box, sat box, etc). If you're using a cable box, you should be feeding 
a capture card via svideo or composite video, then using an external channel 
changing program (and cable).
