I'm having no success with the setup of a "Watch DVD" and "Watch HDD Recorder" activity on my Harmony 1100i remote as the TV does not respond to the input selection commands for HDMI 1 and HDMI 3 which i use for these two devices.

I note that when I use the basic "Watch TV" activity using the database default values for buttons. the Harmony screen buttons for the three HDMI inputs have no effect on the TV whereas the Video inputs 1-3 and the HD/DVD 1-2 input buttons all work correctly and select the nominated input. Can anybody offer any advice as to how to get the HDMI inputs setup? It's extremely frustrating to say the least and I would assume it's solvable but don't seem to be able to find the solution.
