I'm looking to switch from cable to Dish Network. All they offer when I call is upto 4 TVs. I've seen the splitters DP34 I think, that let you physically connect more. Can someone tell me how that works? Do I need two dishes and do I have to pay for two services? It's my understanding that I can't just buy another box off eBay and plug it in, it has to be programmed to my account. Will Dish Network add boxes to the account to support more than 4 TVs and any idea on cost? I'm just tired of Comcast and would like to move to Dish Network.
