I guess I'm just really concerned with whether or not my components have discreet power codes AND whether or not they are in the Harmony database. I guess I'm also concerned with pressing an activity button and then having the TV not receive the signal. Then the remote is "out of sync." That just sounds like a pain. How often does that happen?

I have an SA-XR55 Panny receiver and a PT-52LCX66 Panny TV. Can anyone tell me if those have discreet power codes in the Harmony database? It doesn't seem like I can check BEFORE I get a Harmony.
