how do I hook up my TIVO box to my new Contour 2 non dvr box ?

I thought Tivo was the original alternative to a cable-box.

Found it - The TiVo EDGE for Cable, TiVo BOLT+, TiVo BOLT VOX 1TB v2 DVRs and TiVo Roamio Pro/Plus DVRs are intended for use with digital cable systems only and do not work with external cable boxes, analog cable, or over-the-air antennas.

Translation:  cable-TV subscription, yes...cable-box, no.

I wouldn't use a tivo, they require a cable card and there are MANY people with issues using devices with cable cards. 

The series 2 was the only box that used a external cable box all newer TiVo’s use cable cards and possibly Tuning adapters
