Lizard1977:
After about 90 mins of playing around and experimenting I was about to give up in exasperation, but I remembered your tales of people who had returned their Harmony's because they "didn't work", and decided to perservere. In the end, I started to get a better handle for the way it operates (devices vs activities) but nothing in the enclosed literature or the website really explains this adequately. I've left it for now, and will sit down with the original remotes and draw up a plan of which buttons to map and where, and then construct custom screens of other buttons for each of the activities.
But I have to say I'm a little disappointed with it. I imagined it would be more intuitive and have a better keymap that more closely aligned to the original remote. I'm also stunned that with 5000 brands and 225,000 devices, it didn't know about a fairly common and popular TV such as mine. It's obvious that other TVs in the same range are there, but it wouldn't recognise my model number. But I will try again tonight and hopefully get it working properly...
Your first para hits it on the head - initially it's all over the place until you figure out what functions are all on the additional screens, and you can re-order them.
Ideally, you shouldn't need to go into the devices displays for normal viewing. Eg, if I choose to "Watch Tivo", the standard Tivo buttons are correctly mapped to the hard FF/Play / Rewind buttons, and the additional popular buttons are mapped to the first screen, like thumbs up/down. The second screen ( whilst still in Play Tivo mode, not Devices mode) allows a couple of changes to the sound field of the AV receiver - THX / Pro Logic / DTS settings. You shouldn't need to go into Devices mode.
Do have a look at the Harmony forums, you may get an understading of what is achieveable - the old 80/20 rule applies.
As for the 5000 brands, etc - it's like the Antivirus vendors - " we can detect 10 gazilion virii", but 90% are all variants ...
PS, I don't like the 785, and disliking it more I use it. The hard Play/pause/FF/Rewind etc buttons are just too small, badly laid out and not back lit.
