If I understand correctly, it is different from a normal card with two 
different channel lineups attached to two different inputs in that one 
input gives an MPEG transport stream and the other gives something else.

I might find this patch useful to record a MPEG TS using IEEE 1394 for 
some channels and a MPEG PS using a WinTV PVR 250 for other channels 
from a single Motorola 6200.
