Advertisements Weaknees says No in their buying guide here (bottom or table, entry for "Cable" and "Standard Definition": "Your choices are ... Series 1 and Series 2 units ...". But do they say that only because tuning wouldn't work? Which I don't need. My current setup is a Series 2 TiVo (Toshiba SD-H400, which just broke), an Xfinity cable box, an Xfinity SD-only contract, and a 22-year old JVC TV (picture tube!). I have to set my programs on both units: on the TiVo and on the old cable box, which allows programming 8 channel changes. The TiVo thinks it's changing the channel when it starts a recording, but of course it isn't. I have a spare Bolt, but I strongly suspect it would check to see that there was no cable card and therefore wouldn't let me get to selecting my cable guide. Would any Series 3 (or 4?) work that doesn't have a cable card slot? TIA.
