Hey Thanks, I do have the Nova and got it to control all 3 components. Sort of.
The TV is fine, as it's only the main menu, volume, mute and channels that I need, which it does.
The Pioneer, as I suspected, can only control the main operating functions, which is better than I had (had to watch a movie last night with my inlaws, who speak Spanish only, with no way to turn on the subtitles. Now I can, so thanks again). However, I can't seem to get into the player's actual menu, for setting up the player for different configurations. Not crucial right now, but definitely something I'd like to have.
The Yamaha was the least successful. I found a code to turn it off, but not back on again. None of the codes would turn it back on, only off. When on, I can adjust the volume and that's about it. The original remote had tons of functions on it, so that's the one I'm going to miss the most.
Still, I'm way ahead of where I was 24 hours ago, so thanks again.
