Just a few days ago I upgraded my satellite dish from Dish Type 17 to Dish Type 18. But I see a Dish Type 19 on my "Repeat Satellite Setup" options. What am I missing that's on Dish 19? Which is better, 18 or 19? I know I upgraded to an 18 to get SonicTap channel 815 for some Christmas music as well as some other SonicTap channels as a bonus, and still yet to explore what else is on it.
