Kinda sucks they keep downgrading the thing, a guy over a HtGuide forum said they disabled a pretty neat feature:
"You read it wrong. What has happened is that Harmony has removed the ability to use a hard key to control 2 or 3 different components. An example would be when you have selected the activity 'Watch A DVD' and your system turns on and sets itself up to watch a DVD and the DVD starts playing. 10 minutes into the movie you get hungry and want to get up and fix yourself a sandwich, but the room is dark and you can't see anything. So you press the pause button on your Harmony remote and it 1) pauses the DVD, and 2) brings up the lights by pressing 1 button. After you make your sandwich and return to watch the movie, you hit play and the remote does 1) starts the movie playing, and 2) dims the lights. What is happening is that in the Watch DVD mode the remote is programmed to play the DVD and dim the lights when you hit the play button and vice versa when you hit the stop or pause button. Other examples might be to switch the inputs on your TV and switch the input on your AV receiver or pre/pro at the same time from 1 button."
I think he said they'd be putting it back in (because it "wasn't" supported) around the end of August - but if its a day late they'll wait till the end of Sept. And who knows if it'll be put in then.
