This is probably my first post on the forum in 5 or 6 years - maybe more. I was a fairly early adopter of TiVo products a long time ago (right when Series 2 came out). Through the years I bought many, both for myself and family members. In fact I still show at tivo.com several Series 2s (long gone) with Lifetime service and one Series 3 with Lifetime service (I have it, but think it has a bad hard drive). Plus I have a Roamio that was always month to month and is currently inactive. I also have a mini I bought years ago and never hooked up. At my previous residence, the local cable company used a TiVo-based cable-box, and minis for the other rooms. My wife and I fell back in love with the TiVo interface. We have now moved again very recently and we just have the AWFUL DVR from the cable company. Both my wife and I want to go back to TiVos if we can. The cable provider (Spectrum) DOES have cable cards available. So, time has moved on and I now see "Bolt" and "Edge" models. We are not huge videophiles needing to store 300 hours of HD content. We are thinking that the "Bolt VOX" would be adequate. Then there is an item called a mini-VOX, which I presume is the replacement for the old Mini? However, and I don't know if it matters, we have 2 of the 4K TVs with 2180 resolution. I have one main TV, and plan to have perhaps 2 others using TiVo. Is there anything really USABLE that I already have? The old Series 3, or the Roamio (cable enabled version) or Mini? Or should I just trash everything and start over? I presume TiVo doesn't (occasionally) transfer Lifetime service like in the old days? SO, that's my story. Does anyone have any suggestions as to the best reasonably-priced setup? Many thanks.
