Not sure where to post this. Don't want it to get lost either. All of the sudden my Logitech 880's activities regarding my Samsung TV weren't working right. HDMI1 input goofy. Sometimes it would work, other times it acted like cycling InputNext kind of command. When it used to work perfectly.

After a couple of days of pulling my hair out, trying everything I could think of with my connections and equipment, I decided to go back and recheck all HDMI commands by making custom buttons with each internal command for the Harmony and seeing what those commands actually did.

As I surmised the HMDI1 input command was cycling between HDMI1 and External Antenna. So if the timing was off in terms of equipment response instead of watching what is connected via HDMI1, I'd see local HD broadcast TV.

The "new" HDMI1 input is InputHDMI3V2? Figure that out. HDMI2 is InputHDMI3V3. Works every time now but the labels make no sense.

I have 2 Harmony's so I learned the command to my own label so Logitech can't goof me up again.

PC input is InputRGB. AV2 is InputVideo2V2.

Video 1 seems to have remained InputVideo1 and components seem untouched as well.
