Can someone please explain to me what I need to cut down my cable bill while still getting the live TV I want. I have the tv on almost all the time, mostly the cable news channels and weather center as back ground noise. (I'm weird). So how do I get CNN, FOX, BBC NEWS and the Weather Channel? Do I need Roku? Amazon fire? I saw that Hulu has some live tv. We usually watch TNT, USA, SYFY, Science Channel, FXX, FX, BBC America, Bloomberg, AMC, History Channel and some of the National Geo channels. I'm wondering if I want some of those if I should keep my first tier cable? What about DVR? What do I need if I find I can't live without that? From what I've read I know I'll need an HD antenna.
