When I had the Harmony, if anything went wrong in the macro, I had to go through the annoying process of "is this device on? is this device on? is this device on?" until the system got back to normal, all because Logitech had almost no discrete codes for my equipment.
Just purchased a Harmony One...
Everything, all of it, (Blu-Ray, S3, HDVR2) is working well, It will switch from viewing one to the other. All the buttons work their respective items. Except for the plasma. A Panny TH-C50FH18.
For some reason the remote is just flaky when trying to turn on and off this TV. I wind up resorting to the HELLp button. Which eventually gets the plasma either on or off, but does little good after the next shutdown.
It doesn't seem to be an out of sync problem. When I toggle the remote to the plasma device, few of the soft buttons work at all.
