ray disc

®

 or dVd player that is connected to the hdmI 1 connector. the remote control 

buttons will have different functions depending on if the remote is controlling the AVr or 

a blu-ray disc or dVd player. Appendix A5, Remote Control Function List, on page 25, 

provides a list of the different remote control button functions when controlling a blu-ray 

disc or dVd player.
