My Yamaha receiver model is RX-V383. The Panasonic dvd player is DMP-BD755. Panny remote is N2QAYB000575.

Problem is, while I was searching the owner's manual pdf for instructions re which buttons and in what sequence. Just as I closed the manual to ask wtf the agent had closed the case! This is a bit of a duplicate thread to the one below
