An example of the video stopping momentarily, appearing to buffer, then playing out of sync with the audio can be seen on the MAX channel, movie: The Heat (Bullock & McCarthy). Initially, played with audio mode:off, it provides DD 5.1 audio out of sync with the video. Changing audio mode to leveling or night changes audio to pcm in sync with the video. Changing BACK to audio mode:off does one of two things: either pauses video momentarily with the spinning circle, then resumes playback with a DD 5.1 audio track out of sync with the video, OR the video remains in sync with the audio BUT although the Roku video mode shows OFF, it remains a pcm stream. The only way to restore the DD stream is to stop the video by returning to the UI menu and resuming playback from there. Then you'll have the DD track again, still out of sync with the video.
Duplicated this with the movie "No Sudden Move" on the MAX channel. Also, although this streamed 24p (at times) yesterday, this streams at 60p today.
Seems like a MAX problem, but I first encountered out-of-sync DD audio on Vudu content I purchased. I just switch to leveling mode whenever viewing those; this is a 60's vintage show that couldn't have originally had a DD audio track anyway, so I haven't pursued it.
