I started out with a Dish 500 to use with my original legasy receivers. Then, when I upgraded to HD and locals just a few months ago, I replaced the Dish 500 with a SuperDish that has a third LNB for locals. Now I have an install date for a 622 and I'm told I need a Dish 1000 AND another dish installed to receive all the HD programming (including VOOM) and my locals. Can I just use the two dishes I already have and mount both of them together without getting yet another dish? And what's up with the talk I've heard from my local retailer about the Dish 1000 satellites not being "activated" yet; that one of the new satellites isnt' working currently?
