HDMI input is Verizon FIOS (QIP6200 HD set-top box)

VGA is our Media Center XP computer
All audio goes through an Audigy external expander thingy (how's that for technical?) with IR control that's installed on the MC)
Serial connection from the Media Center to the serial port of the Olevia
Pluses with our setup: With the Harmony 550 you set up each device by selecting the brand/model and chances are, the necessary IR codes are already in the Logitech database so the Harmony gets programmed with those. Next, you set up "activities" (e.g. "Watch TV", "Play Wii", "Computer", etc) where you associate the necessary devices with each activity. Then the Logitech software programs the Harmony remote (via USB cable included). At the end of this process, your activities (and devices) are listed on the Harmony's LED screen with their corresponding buttons. In a perfect world, I press one button to "Watch TV" or "Play Wii" -- you can switch from one activity to another or use the Power button on the Harmony to shut everything off.
So for the most part, we're able to get by with one remote. However, changing sources with Harmony remote isn't any better than with the Olevia remote. This drove me nuts enough that hubby wrote an app that sends an explicit code for each input over the serial code. (I'll have to get those codes from him if you want them -- but I'm pretty sure he found them on the web somewhere, possibly even on the Olevia site). So with that there's a button (on a web page on our internal network) for each input/source. I click the desired source/input button and go right to it. He wrote the software in Ruby but if you're familiar with Win32 and serial port stuff in a different language, that would work too.
Some minuses: on HD 5.1 channels we're seeing up to a half-second delay between the video and audio when using the digital optical from the 6200 to the computer/Audigy (audio is delayed) so that's back to plain composite/stereo
(However, that may have more to do with some driver issues than with our setup).
I seem to have broken or permanently confused the Audigy/IR a few days ago so we're no longer able to control the volume for all inputs/sources with the Harmony and have to do it via Windows (mouse/keyboard).
We're still futzing with the audio in other areas too as we try to get MC XP working smoothly with the latest updates but none of that has anything to do with how well the Olevia works which is quite well
Not sure if this is the kind of information you were looking for -- if you have specific questions, I'd be happy to answer them. I hope to find a way to have the Harmony programmed to do direct input/source switching but that's a little lower on my list of priorities at the moment ;-)
