Just got MySky HD a couple of weeks ago and trying to get my Harmony 75 working with it. Read up on the forums and have set it up for the TDS-850NF as suggested.
Everything works well except that on the guide and you press up or down, it skips 2-3 channels at a time.
I have set the Response to '0' so you can 't get any lower than that.
Has anyone had similar problems and how did they fix it?
