Newer panasonics have a button that goes straight to Netflix. Load
THIS into your JP1 remote and see if the Netflix command works on the 65. If so, teach it to your harmony. If not, you can easily customize your activity to add commands and delays to the beginning to go directly to Netflix (for example: discrete on, wait, vieracast, up, ok), so long as your aren't using myharmony.com to do your programming.
As I said before, confirm IR is totally unnecessary in your case. So it's pointless to even try various menu functions.
