I had a little problem since my dish was blown down with the high winds, i took the DVR to the living room to watch some movies, but after a while the movie would just not show up. I would press the movie and the screen would be black. I plugged in the SAT cable and it worked, even though I did not have a signal. So does that mean that I could not take my DVR to my parents house and show them a movie that i recorded. Or would it have to be connected to a SAT Dish?
