Thanks, great help with this and the other idea about how to handle lack of a discrete power off. Very elegant solution.

One clarification. The Sony has two similar sounding inputs:
1. "Network" which is for a home DLNA network
2. "Internet Music Services" which is for things such as Pandora or Spotify.

"Network" codes are readily available in URC's db, but "Internet Music Services" are not.

Did you mean to say "Internet Music Services" when you listed your codes in Post 5?

Again, thanks!
