After my last remote update (changed audio receiver source since replaced the analog audio from my TV to the receiver with Digital Coax) the On and Off options under Device options are no longer present. Any ideas?

I would rerun the setup for that device and look at the On/Off settings.

This happened to me one time when I changed the setup of my HD DVD player. I reran the setup and told the software I had the original remote. It then had me teach the commands, and when I finished, the On and Off buttons were back.
