said by banditws6:Because Comcast's billing system is literally unable to support proper pricing for CableCARDs in a two-tuner device, they see each tuner as a separate box and bill for an additional HD outlet. Thus, a manual discount code must be put on the account to reduce the price to the correct level.
This MAY be true in your area, in most if a second card is in the same piece of equipment then there is a reduced cost for second card. Has been like that in New England area for a few years.
