^ OK, since we are talking about workarounds now, I guess I'll need to lay out my current findings.
First of all, I'm using a Beta sample 105 at the moment, so it is not absolutely certain that what I'm seeing actually applies to the 103. I suspect it does, but I can't confirm that.
Second, I'm on newer, Beta firmware than you folks with 103s. So I'm going to try to recall my set of results that match the 1018 firmware currently on the 103. The answers for the Beta firmware I'm using are DIFFERENT. I.e., firmware changes are in process to address this stuff. (I can't talk about Beta firmware beyond that.)
Third, some of the errors we are seeing now appeared late in the Beta test cycle. That's unfortunate of course, but it is what gives me complete confidence OPPO can fix this stuff in firmware. I.e., it used to work!
So here goes:
I have only HDMI 1 cabled. Folks who are using both HDMI outputs will likely see different results. This is one of those matrix of testing items I alluded to above.
I use a variety of calibration discs to check this stuff. It is vitally important that you use test content of known quality regarding sync. Real movies *OFTEN* have inherent sync errors that may even date back to their theatrical release (i.e., it was that way in movie theaters, too!). Such inherent errors typically change scene by scene. There are lots of ways for such errors to creep into movies, and as many reasons why the errors were never corrected. How it happens is not as important as recognizing that it DOES happen.
One of the best, readily available, tests right now is on the Disney "WOW World of Wonder" calibration discs, which are available in both SD-DVD and Blu-ray. I use both of those and other test charts as well.
For the 1018 firmware:
Shiny disc playback (either SD-DVD or Blu-ray):
1) HDMI 1 video lags HDMI 1 audio by 150 ms. You need to add 150ms audio delay external to the player.
2) HDMI 1 video lags multi-channel Analog audio by 75ms. You need to add 75 ms audio delay external to the player.
Netflix streaming (native app):
1) Audio / Video sync is *CORRECT* for HDMI 1 video vs. either HDMI 1 audio or multi-channel Analog audio. This is based on using Netflix' test streams of known quality.
1) HDMI 1 video is AHEAD of both HDMI 1 audio and multi-channel Analog audio by 150ms. Since video is already ahead of audio, adding audio delay will just make matters worse. Since there is no way to speed up the audio or delay the video external to the player, there is no workaround. We'll just have to await a firmware fix.
NOTE 1: At one point, the answers above were different depending on whether the player was set to 1080p/60 or 1080p/24 output, specifically for the multi-channel Analog results. I'm sorry, but I can't recall whether that was true for the 1018 firmware. There's that matrix of test combos again....
NOTE 2: I don't test media file streaming, so I do not know if there's a different result for that. My expectation would be that audio / video sync for media files would match the Shiny Disc results.
NOTE 3: As should be obvious from Neuromancer's post above, different Beta testers are seeing different results on this. My assumption is that this is simply due to variations in configuration (e.g., 2 HDMI cables instead of 1, etc.) But that's yet to be confirmed.
