We just purchased a great room set up with a Pioneer Elite VSX-53 as the AVR. I'm using a Harmony 650 as an interim remote. The remote worked fine on my main system (Meridian) so I expected the VSX would be simple. Not so. After setting up the remote, the unit will turn on the AVR, the TV (Panasonice Plasma), and the STB or Oppo - then it seems to send another signal and the AVR switches off.

If I use the VSX remote to switch the AVR stays on. If I use the Harmony help function the AVR stays on. I've been through all the Harmony "help" options, changed the order in which the units turn on/off, etc. I've been through the VSX-53 manual in depth and tried changing various settings. No luck. The only setting I have not changed is the Harmony key delay and since I couldn't find any reference to that subject in the Pioneer manual I left it untouched.

The VSX appears to use a toggle on/off rather than discrete commands (argh)...so short of buying a different remote, any suggestions?
