I too followed these instructions and am at this point. The disc is selected, but the display doesn't go away. It appears that the commands for turning the display off are being sent too quickly to the device. There needs to be a longer pause there in that one spot. I'm using a 676 btw..

Also, has anyone been able to program a macro to lock and unlock the door.. The "return, enter, power" thing gets old and is cumbersome on the harmony. How can I set this up on the harmony?
