I currently subscribe to Directv and want to have 2 more rooms wired in my home. There are many deals for free installation and cheap receivers, but they are for the most part limited to new subscribers. I have heard that I could cancel my service and re-up under a different name (I'm thinking about putting the service under my dog's name). Has anyone had any experience doing this? How long do I have to be disconnected? What are the ins and outs of the deals?
