It is hooked into our network somehow here at home. We have a program on our laptops that enables us to launch the slingplayer from where ever we are. As long as we have a high speed connection, we can watch tv. So when we are at my parents in Michigan, dh can watch the hockey games from CBC on his computer. Which was one thing he really wanted it for, since he seemed to always miss the Leafs and Habs playing.
They also have a new thing coming out called the SlingCatcher. I'm not exactly sure what it does, but my husband wants it. lol.
I bought him the slingbox just before they launched their new boxes, so I got it at a good price. I noticed the new ones are quite a bit more. I don't use it that much, but dh watches tv at work sometimes.
