I am trying to program a 620 with the Dish 322 receiver and a Samsung 550. I have experence with Harmony remotes and have had good luck with them in the past but i am having issues with this combination. The first problem is i can't get the TV to respond to the input command to change to "TV" and the second problem is i can't get the 322 to turn on or change channels, anything. From what i can tell the 322 is not RF and the 620 will work for DVD, CD...

any help would be appreciated.

Never mind, the codes downloaded from Logitech were faulty. once i reloaded them everything worked.
