Because every cable head end is different. There are several different manufacturers of head end equipment, and the customer side equipment has to match. I'm not aware of any manufacturer's tuning adapter that works on a competitors system, they are all proprietary. Someday, if Tru-2-Way ever comes to be, the required firmware for each cable company could be downloaded. But we are a long way from that being universally implemented. Its the same reason why the cable card is not built in, you need one that matches what your local cable company uses.
