I was dumbfounded when my Yamaha RX-A8A Aventage AVR started jumping scenes for no apparent reason. I would setup to go to Apple TV and after momentarily choosing that input the AVR would jump for no apparent reason to either TV or DishTV. First I blamed my Harmony Ultimate remote but no amount of tweaking the programming fixed it. Finally I read in a forum somewhere that enabling the HDMI Control may cause similar issues. So, I went into settings for the AVR and disabled HDMI Control and the problem was gone. There should be a warning about this in the manual! Anyway, I just wanted to share this morsel of knowledge with you guys. I just love the sound and video quality of the Yamaha RX-A8A, but it does have some quirks! Happy New Year 2023!
