Need to have Coldsteel, or somebody on the inside, weigh in on this one. I don't have Starz, I have never had Starz, I have always had Encore 340, with my 250 package, I have had the Encore East for as long as I can remember,and I still have Encore 340 in HD today. Now I do have the Platinum Package, and I did notice that on the webpage That Encore East(340) is no longer included in the AT250 package, and this is something new. All the other Encore channels are included though.
So we need to find out if Encore East is in Platinum and Starz.
I have Platinum so it's not part of that apparently, but I don't have Starz. Like I said this sounds like a new development to me despite Dish's CSR (actually he was one from tech support) assurances that it's always been this way.
