I am planning on buying 2 new Tivo Bolts from Amazon. I am switching from Dish Hopper to Cox Tivo. I currently have a half dozen 2 TB external drives full of content for the Hoppers. That content will all be lost once I switch to Tivo. Can I use those drives as expanders on the Bolt and swap them to view my Tivo content, OR was the Tive salesman correct when he said disconnecting a drive from the Bolt will erase all the content, because of DRM. It doesn't make sense to me that unplugging a hard drive could erase it. On another note, can one Bolt View content on another Bolt through MOCA or Ethernet?
