The funny part, I found, was at least in my area, the techs don't always know about 61.5. I learned about it on these board!
When I signed up with Dish (a very happy DTV convertee), due to trees, they couldn't pull down 129. Well, after reading here, I called Dish back and said I wanted a tech to come out and put up a 'wing dish' (their term) and point it at 61.5. After getting a 'supervisor' (haha) that claimed that wouldn't work, I called back and got someone else to come out who just did what I asked him to do (imagine that!) But when he came down from mounting it, he said "so 61.5 is supposed to have your HD content?" I laughed and said I learned that on the forums and showed him! He said "learn something new every day!!"
I thought that was odd, but I sure was happy he did what I asked!
