Shoot. That's the only code I've got. Was hoping it would do the trick.
In the meantime, I taught the Harmony the Input selection menu from another remote and have the two-step macro in place. It works reliably and only lacks elegance since the Input menu flashes on the screen. I expect it'll do.
On my Panasonic Plasma installs, to switch directly to the TV Tuner i create a 3-step Macro ( 2 dot 1 ) which forces the TV to tune to OTA channel 2.1
I like this method better than bringing up an Input menu and scrolling, or using Ch Up/Ch Down as it will end up going to the next higher or lower channel than what it was on previously. Going directly to ch 2.1 is clean and quick, and is a consistent reliable anchor for entering TV Tuner mode.
It also works on Sony LCD TVs.
If you have to do it using the Input Menu, you could add the Exit command to quickly clear the menu from the screen.
. The go-to channel idea is a good one. I am using the Input+1 macro right now and the Input menu exists immediately upon input selection, so it is pretty fast. I actually think I can shorten the button delays for the set and do even better. The defaults are overly generous. I might compare the two options and see which one is quicker.
As a general follow-up, after going back and forth with Logitech support, they officially changed the InputTV command in the profile for my specific model to the two-step Input+1. They couldn't come up with an alternative.
