I have a wierd problem with my Yamaha RX-V563 reciever. I have my Motorola DCH-6416 set top box hooked up thru an optical cable. Sometimes when pushing a button on the remote for the set top box, the volume changes on the reciever. I may have the volume set at -30 db and it will change to -35 db or -29 db. Doesnt seem to matter what the button on the remote is. I thought it was something wrong with the receiver so I took it back and the dealer replaced it with a new one. I hooked it up and it does the same thing. I have looked at all the settings in the menus and cant find anything I may have done to cause this? Anyone have any ideas? Yamaha was no help.
thanks
