First, TiVo launched it with the only solution the cable cartel (via their front organization CableLabs) will allow. There is no approved two way device that would allow TiVo to keep their UI. The only two way communications device CableLabs has/will approve is using OCAP, which allows the cable company to download whatever software they want to the box. That would mean TWC could put that god aweful Navigator software on your brand new TiVo. That's no choice at all. Second, you can't use a cable box with the TiVo HD or S3. If you want to get encrypted digital channels (including HD channels) and can't get them off the air, you need the cable cards. Don't like it? Complain to the FCC. Their the ones who have let the cable cartel make a joke of the decade old mandate.
