I had a couple of AVR300 demo models in my home and bought 1 myself as well. My own model contains the 2.90 software and I noticed a strange thing. Wonder if you people have the same issue or not. When I push the "mode" button on my remote to shift through the different sound-modes it very often "skips" a sound-mode. I see the mode being selected on my AVR300 but it then immidiately skips to the next mode. I still have the same remote as my first demo avr300 so i can't be the remote. is this a hardware problem or software ?
