They both seem to do the same thing so I am trying to figure out the difference between DishPro UHF 6.0 and DishPro UHF 8.0. I think the 6.0 remote comes with the 522 and the 8.0 comes with the 811 if I am not mistaken. Also why did they go from 5.0 to 6.0 on the UHF PRO remotes? Whats the difference in these?
