My kids have a SDTV in thier room right now. What are my options if I just need a SD DVR to work with FIOS? Is there a Series 2 TiVo that will work with a cable card? If not - how does one hook a S2 TiVo to a regular cable box? Do I just take the video out of the cable box and stick it to the input of the TiVo box? How does TiVo control the channel changing? Thanks so much! Sorry if this is the wrong forum - I didn't find a S2 forum.
