Alternatively, you could just get another tuner card, so you have one on the 
direct cable, and the other via the tuner box. In fact, you would probably need 
to go this route, since the selection of channels available 'off the cable' and 
'digital' is going to be different. Because of this, you will need to set up two 
different sources in mythtv, and allocate one to each stream received, that is, 
one to each tuner card.
