Dish can sometimes be incorrect from time to time on its site or may take a while to update, but for the most part, this is correct or should be correct. Of course, Center Ice is not included although it is listed.
I was trying to be helpful. I was pointing out that I had asked the same question as the OP, and even had a conversation with a DIRT member about it, and I provided a link to the other thread where I posted the answer I received, rather than re-post the entire previous conversation. Sorry if I offended you.
FXX and National Geographic are the new "perpetual preview" channels, just like AXS used to be. In other words, they are not "officially" part of Welcome Pack until the preview status ends. I still get FXX and Nat Geo on my deactivated receivers that still work for free preview channels. AXS was in "perpetual preview" mode for four years before it was officially added to Welcome Pack.
