Had my HR20 for 2 days now. Still trying to get used to it, and get my Harmony to work correctly with it. Big issue I am having now is how sensitive it seems to be when I enter numbers. Try to change to channel 296 (adultswim and it keeps doubling up some of the numbers, so it tries for channel 2296 or 2966. I sat in the guide for a minute trying over and over. Has anyone else had this issue? It has happened on the original remote but seems extra sensitive on the Harmony 880.
