I am fixing to change out my dish 501 pvr (god I am going to miss not being able to record) to an 811 HD receiver. Can anyone tell me when I call to activate it if i am a subscriber to the top 180 with the HBO/Cinemax package weather or not my dish 500 will receive the HD channels and or will I also have to subscrbribe to the HD package and pay the extra 10 bucks a month?
