I bought this thinking that I'd be able to watch sports games that I had recorded on the DVR. But I used it once or twice, moved the TV and never set it back up. Now we have dropped the cable because we just don't watch TV much these days with two little kids in the house.
It's a Slingbox by a different company. Watch your cable box and DVR/Tivo from just about any computer with an internet connection. Same deal for many smartphones.
