Sorry if this has already been asked, but I couldn't find anything by searching. My cable bill is out of control. I am on the verge of canceling my cable altogether. I have a Tivo Series3 so what I wanted to know is: Without a cable subscription, when I plug my coax directly into my TV I still get some channels. Will I be able to plug the coax into my Series3 and have it recognize these channels and be able to set season passes and recordings using the guide? Or will the channels be mapped in way that the Tivo won't know which channel is which? I figure in that case, I should still be able to set timers based on time and channel. Or will absolutely nothing work? I have tried an antenna but where I live I get absolutely nothing over that. That is not what I'm interested in. If it makes any difference in your answer, I'm in Manhattan, and the cable service I'm planning on cutting off is Time Warner. If anyone has any experience with this I'd love to hear about it. Thanks.
