I also turned off the internet/wifi operation, to make sure that wasn't the cause.
My Oppo is connected to the OLED via HDMI for video, and for audio I use the analog outputs. If I connect both audio and video from the Oppo to the TV, via HDMI, the problem is corrected.
To make up for the video delay while using the Oppo's analog outputs, I set the A/V Sync on the player to 160 ms, which is near max. I'll keep it there till I find the cause.
In the meantime, I've ordered the Disney Wow disc to dial in the correct setting for the A/V Sync.
Edit: confirmed with the Wow disc, the video is late, or the audio is too early, which ever way you want to look at it.
With the A/V Sync on the Oppo player set to 0, the rotating line on the test pattern beeps at the 166.6 milliseconds, which indicates the audio is too early. That's if I use the analog outputs (I'm not using my AVR right now and I haven't tested the digital audio output on the player, except when I turn off the power amps and use the internal speakers on the TV. With internal speakers, the audio and video are perfectly in sync)
Like I said, setting the A/V Sync to 160-170 milliseconds works for me with the analog outputs.
Iam a reader from sweden who can actually give you some input on this issue has I have had a lot of lipsync issues in my various setups.
As I understand it you are connecting the Oppo player straight into the Samsung Oled. The thing is that HDMI connected appliances communicate with each other. One of those crucial things that gets informed over the HDMI interface is lip-sync audio delay. The display tells the player how long its image processing time is taking, the player then automatically adjust for this value (delays the audio) over the HDMI interface. This was a feature introduced in like HDMI 1.2 and has been improved in in HDMI 1.4.
Sometimes, this communication is not properly negotiated due to incompatibility between HDMI devices. Different manufacturers are suppose to work perfectly with each other but some don't. Picture always work pretty much but lip-sync audio is of course a more hidden feature that can sometimes get screwed up.
The funny thing is that this skew-up in communication can sometimes generate really odd results. For example, my Philips TV cannot communicate properly with my Yamaha receiver. The audio delay is suppose to be 150ms but the yamaha always interprets the Philips TV HDMI information as 180ms lip-sync delay. The result is constant lipsync issues. By contrast, my Denon amp is always perfect with my Philips TV in terms of lip-sync.
Consequently, in your case I am betting that the Oppo player and Samsung OLED is not communicating properly over HDMI. Your Playstation 3 on the other hand is. The solution is to get a home cinema reciever that can properly communicate with your Samsung TV and your Oppo on the side of the chain. In my experience this works in a majority of cases but dont count on it. Ask to try a homecinema amplifier and evaluate it at home together with your setup. I have been amazed by the number of people suffering from this. In cases were the communication is not working, turning off image processing and things like that can help but It does not necessarily have to. For example, I was screwed with my Philips TV, the processing was always 150 ms no matter the amount of "image advancements".
You can ofcourse always set the delay manually. However, when I do this in my setup, I notice that this does not always fix my problem. Suddenly, switching a channel, and the lip-sync is abit off again. Hate it. Once you have a working HDMI lips sync communication set-up, I believe the system is constantly adapting the lip-sync to these small of hicc-ups, keeping the lips-sync in place despite changing channels or pausing a blu-ray player. With a manual audio delay setup, you miss that adaptiveness.
