I also have a Harmony remote (the 676). Like the 688, it has both Activity and Device modes. Unlike yours, mine is state-aware. So when I switch from "Watch a DVD" to "Watch TV" in the activities, the TV and receiver stay on with no problem, and everything changes input settings correctly. It works great, and it's been a lifesafer for my in-laws and my parents, who never could figure out the old "universal" remote.

The only problem I've had with this remote is that my blasted Sony Wega TV doesn't seem to have direct codes for changing between widescreen and 4:3 mode. So I actually had to macro the "Watch a DVD" activity to always put the TV into widescreen mode. Unfortunately, that means that when my kids watch a DVD that really is in full-screen mode, I have to switch the remote over to Device, select TV, and navigate the darn menu system, then switch back to Activity mode.

If anyone has a Sony KV-27FS12 and has figured out the direct code for changing the aspect ratio, please let me know!
