I was reading on the dish forum where you can not back up live tv or a live show you are watching on the Hopper 3. What I mean is my wife likes to leave our DTV DVR on the News station when she goes to bed. The the next morning rewind it back a hour or so and then FF through commercials. Does it have to be recorded to do this on the Hopper 3 ? One of the great thing about a DVR is that you can pause LIVE TV and then start right back up where you paused it from. If anyone could please try rewinding a live TV show on their Hopper 3 they are watching( NOT RECORDED) and tell me how far you can rewind the LIVE show I would like to know this info.
