Tivo Series 3 gets thumbs up from CableLabs and 180-hr Series 2 box disappears

TiVo's HD-ready Series 3 box just got one step closer to being real now that it's been certified by Cable Labs. Sure, the cert may not mean as much as that golden FCC blessing, but it allows the box to be sold as compliant with various cable standards, including CableCARD. Meanwhile, the dual-tuner, 180-hour TCD649180 and 80-hour TCD64908 Series 2 boxes appear to have vanished, after initially appearing for pre-order on Amazon. We'll leave the rationale behind that to the conspiracy-minded among you. We're gonna keep waiting for Series 3, and hope that the dual-tuner, big-drive model stays in place for those units.
