I bought a Bolt and then a new Sony 4K TV. I have tried 4 different antennas, all of which work fine on my Series 3 TIVO. Not so with the Bolt. Out of 17 possible channels it gets 6. I've been on the phone with TIVO twice, and have chatted with a rep online. This is what a supervisor finally admitted to me: the Bolt has new software that doesn't pick up channels as well as older machines and there is nothing they can do about it. So, unless I get cable, I have a $300 bookend. I am seriously unhappy with TIVO right now. Another TIVO user told me they have started selling their stuff to cable companies so they don't need to consider antenna users. I REALLY don't want to get cable, but after the base cost and only one year free--and a ridiculously high price for lifetime--what else can I do?
