I have a Tivo Bolt. My data use has been 450GB a month when we were not even home on a month long vacation. And I was only recording a few hour-long HD news programs a day during that time as I recall. My question is: are all 4 tuners using the data stream all 24 hours even when they are not recording? I assume so, since the 30-min recording is always on. Can I reduce that data by putting a couple of the tuners on the Xfinity default Channel 1, which only seems to show a low-definition video in the upper right corner of the screen?
