I have 3 Tivo Premieres, 2 that I've upgraded to 2tb hard drives and 1 that hasn't had anything done to it. Problem is that I no longer have, nor remember what software I used to upgrade the two, because now I want to upgrade the third one. I already have the hard drive, but I need help with the software. Does anyone know of any recent or relatively easy to use software to upgrade a TiVo premiere? I would very much appreciate all suggestions. It's been about 3yrs since I've done the upgrades, that's why I don't remember what I used. Getting old I guess.
