5 commands isn't enough for me either. I have a sequence to run RCE DVDs on my region free HD-DVD player that takes about 9 key presses.

First thing I thought was to join two sequences together but as you say that's impossible.

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.

Ok, part of the problem is that while the tivo will accept signals bounced of the ceiling, the plasma won't.

Because it's sending commands to multiple devices you do have to hold it up longer than a regular press particularly with some of the defaults where it may wait seconds between presses depending on your device. This can require a fair bit of trial and error when you first set things up or get a new device.

I noticed that. The problem I'm seeing, is that once the TV fails to start as part of an activity sequence, additional attempts to repeat the activity, also fail to start the TV.

It seems that, once the Harmony One thinks the tv is on, it refuses to resend tv-on commands. That kind of makes sense, if the tv-on was a toggle, instead of discrete.

For my folks, I need it to be simple, if the activity fails, repeat it, but make sure the remote is pointing at the TV. That stupid help yes/no cycle isn't going to work. They won't put up with it. Heck I won't put up with it.

Press the off button, then try again.

When you first press the Help button, any discrete power commands should immediately be (re)sent, even before you respond to any questions.

At least that's how their software has always worked in the past.
