I just saw a twitter comment about HD only packages that I'm not convinced of. A user asked Dish what happened to his SD receivers if he upgraded to an HD only channel package. The agent told him he would have to upgrade all of his receivers to HD receivers to receive any of the programming. I myself have though about doing this, but I have and HD receiver in one room, and an SD in the other. I can currently watch what appears to be the HD channels on the SD receiver, it's just not in HD of course, which I don't care. So why would you have to upgrade all of your equipment? Kind of long post, but got me curious. Thanks in advance for any replies.
