I have a TivoHD that I upgraded some time ago with a 500gb drive that we are quite happy with. I am guessing it is somewhere around 5 years old at this point, but it is rock solid and does everything we need. That being said, due to various reasons, we just feel like we aren't getting our money's worth out of our cable TV subscription anymore. The shows my wife watches are largely on major broadcast networks, and I find myself watching stuff from Netflix or on DVD/BluRay when I have time. My main question is this: we have a collection of copy protected shows (we are on Cox where almost everything is copy protected) that my boy likes to watch that have been recorded over time. If I yank the cable card and tuning adapter, cancel cable, and hook up an antenna, will these shows still be watchable? A few other related questions: What is the actual procedure for reconfiguring the Tivo for antenna only recording? Do I just shut it down, pull the cable card, hook up an antenna and do something like guided setup again? Is it possible to have an antenna and cable running at the same time on a TivoHD? Not that I couldn't hook the antenna right up to the TV to get a feel for signal quality... Thanks in advance, I have benefited enormously over the years by lurking here.
