Thanks Guys, I thought this was wierd, because people are still buying and selling older dish recievers, including 811's on ebay, and if it won't work, what's the point, unless they are dealing in unusual and very expensive door stops.
I have the answer. I spoke to a Dish Network installer today and he told me that the original satellite is still up there broadcasting MPEG2, but they have a newer satellite that is broadcasting MPEG4, with more content. Case closed. Thanks
