I've been a TiVo subscriber for almost 7 years now and hope they're around for a lot longer. As a Cablecard user, I've given up on-demand and PPV in exchange for having my own set top box. The change to SDV will only make things worse. I'd hate to give up my TiVo in exchange for a box from Comcast. My TiVo has a nicer UI, better recording options, and allows me to stream Netflix.
