You can't do this.  Anything you get from the card has to come through 
the MPEG encoder, which can only handle one stream at a time.  Even with 
the analog V4L cards, which don't have encoders, only one stream at a 
time is sent to the PCI bus.

Think of it as a A/B switch... turning on one input effectively turns 
off the other.  You can only use one at a time.
