This is a whole new world that I'd never heard of!
What documentation are you using? What models are the clients?
By the way, just using the IR remote, we had a ridiculously squirrely thing happen with a wireless client and a Sony TV: two different clients worked fine on other TVs, but on this one TV the client power light came on 15 seconds after we hit power and the picture didn't come on totally until 45 seconds after hitting power.
So, just a weird suggestion: try the commands you've got, but with the clients conencted to TVs other than the ones you've had them connected to.
LOL, we have been controlling directv receivers, genies, and clients for 3 years! what type of control system do you guys use?
