Pardon Sir…but I think you'll find that the Motorola SB's Broadcom BCM 3348 chipset was limited to a single tuner albeit (euro/cable labs) DOCSIS2 certified upto 55mbps downstream (upto 1024QAM) and 30mbps (256QAM with S-CDMA) upstream. However even though quite impressive originally with it's 200MHz 32bit processor it's 2002 legacy architecture is now starting to show it's age and single stream is all you'll get whether your approaching the enemy from the front or enfilading with a rear flanking tactic, albeit good for upto 860MHz!
