I got a call from Dish some months ago about this. I was using 110, 119 and 61.5 and they told me I had to reconfigure to 72 as they were moving the programming off of 61.5. About a week later they called again and were a little more insistent. So, I moved the dish to 72, called and they made whatever changes and I didn't think much more of it...until I realized I was missing a few HD channels. When I asked them about that i was told they had not moved them all yet.
That's fine....now, here we are about two months later and I called yesterday to ask about my missing channels and my answer was.......gee, we don't know. And, more interesting was they told me I could move back to 61.5.
So, I am thinking they are not real sure what the heck they are doing or are going to do. I don't want to be out there moving the dish around especially right now as it's 10 freeking degrees. So I guess I am to just continue paying for channels i am not getting. Apparently they don't mind.
