Why not deal with Oppo customer service directly? I wasn't even aware they had an authorized dealer network???
Oh and I've owned DVD and Blu-ray players from: Panasonic, Oppo, Denon, and Marantz, etc. To date I've never had a Denon last me more than 2-3 years without some reliability issue including their flagship DVD-5910. I had similar issues with Marantz. I had a couple of minor issues with Oppo most of which was fixed with firmware updates. Nobody is perfect, but Oppo has GREAT customer service!
