Do I HAVE to have a HD set to use the new SKY HD box? The reason I ask is that I'm moving to a new house and will finaly have room for a projector. I'm going to get one that can do HD but that will be a month or so after I have moved in. MY plan is to get SKY HD for my main room downstairs and use my current SKY+ box upstairs as the 2nd box in a Multi-room setup. So until my projector arrives I will only have my none-HD 42" Panny plasma downstairs. So my question is will I be able to view the normal none-HD chanels on Sky from the Sky-HD box on my plasma? And will Sky demand I have a HD device on site when they come to set up the dish & box? Thanks for any Info.
