I'm way in over my head technically on all this stuff, but was trying to figure out which of the newer Tivos would work with our cable arrangement. We're on basic cable, which is only analog. I'm assuming that all the programming is SD, too. We're currently using Series 2 Tivos (great products but energy hogs). So key question: Do any of the newer Tivos work with analog cable? Alternative solution: Switching to over-the-air One alternative is to switch everything to over-the-air HD antennas (we have one Tivo set up with that), but that's flakey where we are--intermittent reception, incredible sensitivity to orientation of antenna, etc. Plus, and this is key, Tivo does not provide programming information for NBC in our area. That's been true for 3 years now and continues in spite of my repeated requests for them to fix it!
