One MultiStream card can decrypt six shows at a time.  While this only 
has three tuners, the Ceton card has four tuners running off a single 
cablecard.

I don't know if this is a technical limitation of the CableCard system, 
or just one in Silicondust's design.  The HDHomeRun Prime has two 
operating modes.  With no installed card, it functions just like a 
3-tuner HDHomeRun.  Each tuner can record multiple streams through 
multirec, up to the soft limit of 5 imposed by MythTV.  With a card 
installed, each tuner only allows a single stream, meaning you can only 
record three shows simultaneously.  Do understand that you will still be 
replacing three cable box rentals with a much cheaper multistream card 
rental.
