The buttons (IR-signals) seems to be all mixed up on the 650 "universal" remote (EU-model) when used with Denon DVD-players. There is only one Denon-code on both the 650 and 750-remote, but 750 works (with Denon-players and the 650-receiver). Tests on lots of newer and older Denon-players and with Denons own universal control indicates that no Denon DVD player can be controlled with 650! The Denon uni-control can't produce the same signal-button configs that the 650-remote with "Denon DVD"-code does. A minor mistake of course, but Yamaha Norway claims they never makes such mistakes and refuses to give me a 750-control for free or with rebate, and cannot give me a 650-control that works (have tested a couple). Any views?
