the MX- 850 will do more for you than Harmony can. Note there is no help button
Universals editing software is truly not for a just anyone to use it is intended for technicians. So to help you start at the program pull down. If it is not listed in there try all TVs in your size range. If that dose not work try all the [Panasonic1-11]. The nice thing about an MX-850 is you don’t have to use the codes. You can use the lean feature this is very fast. All you need to do is look for the icon on the “Edit and label buttons” window that has a remote with an arrow pointing in to the remote. Also like the harmony the macro’s are very nice. Just hit the Rec button and do what you need to do to make the tv land on the right input and the DVD powering on and amp changing to the right place and so on.

Also when looking up the IR codes change the pull down “IR data from:” to audio or tv so on…
