Sorry you're having issues.
For me it's strange to read all of the chat about Netflix/streaming issues let alone the 0, +1 sharpness complaints. I still own/use my 93 that I have had since pre order days, mated to a PJ and 126 inch screen. My 103 is mated to a 60 and 50 inch Plasma. Nock on wood, and I'm completely being honest here, yet I have yet to have a hiccup beyond picture quality due to bandwidth/IP provider slowdowns when it comes to either Netflix or VUDU (even Blockbuster (93)) on either the 93 or 103. And I couldn't even tell you how many streaming events my teenagers have logged in the last 3 to 4 years. The 93 has a handshake issue with the PJ every once in a while yet its running on the ISO-capable firmware of several years back - reselecting HDMI input via the remote fixes that. The 103 I keep firmware current and its been flawless.
As mentioned, OPPO has some of the best customer service in the industry. Known/reproducible issues get resolved and those that need replacements or refunds get handled quickly and professionally. The OPPOs may not do everything for everyone perfectly. The enormous variables between components and configurations effect each player / manufacturer now days. Hope you get things worked out.
