What's that? If you don't mind "sharing"...
Bell ExpressVu (BEV) and Star Choice (SC) are the two Canadian dish-based satellite systems. The two have more programming than the US services, and while some channels that have the same name north of the border duplicate American choices directly (CNN, Fox News, etc.), others with identical names have different programming (HGTV, Discovery, Food Network, etc). And yet others have different names and different types of programming (Space, MuchMusic, TSN, etc.). Finally, there are other networks with some programming that is not available in the US at all (BBC World, APTN, NHL Network, etc.).
Add to that additional news choices (BBC World, EuroNews, CBC Newsworld, CTV NewsNet, et.al.), and the US broadcast networks from both the east and west coasts (Seattle or Spokane in the west; Buffalo or Detroit in the east) without jumping through major hoops.
Because of the exchange rate, you make out a fair bit better cost-wise as well.
The services are only available in the US through a "grey market." The companies cannot sell to you directly, but an American (or a Canadian who is living here in the "southern provinces") can use the services of what is called a "broker" in order to maintain a Canadian address and facilitate billing.
