Some cable systems such as Cox Fairfax use Switched Digital Video (SDV) to carry multiple channels on a single band. Using solely a cable card does not allow the reception of the switched channels. So it is not merely On Demand services that are impacted when attempting to ditch the less than aesthetically pleasing cable box, channels that are supposed to be part of a standard package become inaccessible. Cox Fairfax has been fined by the FCC for this practice, however they are not relenting in their use of SDV. I cannot speak to the quality of Fios as it is not installed in my neighborhood in spite of Verizon imploring me each week with glossy adverts to make the switch. I guess whatever subcontractor does Verizon's direct mail marketing either doesn't know or doesn't care that it is unavailable at my residence.
