Better options
With the latest windows media centre you can streem TV from one box set up with the tuners to others in the house - as long as they are also on win7. As such this product become obsolute to all but mac users - which I bet can do the same anyways.
So why pay that much for somthing that requires its own propiority software when a standard dual tuner can be yours for £30 to £55 depending on brand, does all this and more. Infact for that sort of money I can build a basic media server with a dual tuner to do the job and a hell of a lot more...
