You can't merge two divergent signals that way. It would be possible  
if you were talking about joining VHF and UHF antennas together  
(dating myself there), but an antenna signal is different from a  
cable signal. Besides, how would Myth decide how to tune it?

Consider buying a second card - is might cost more money, but it is  
the easiest way to go and you'll avoid the headaches.
