I used the manual IR entry found on this screen.

I programmed the CD command into my TV setup (using the Pronto codes fond on this site) and it did start the CD player. The harmony has a much more limited range than a Beo 4. The harmony seems limited to about 6 or 8 feet. The Beo 4 seems to work no matter where it is or pointed. You don't even need a line of site some times as it will pick up stuff bounced off of walls.
