In earlier releases, when the main movie is in multiple m2ts files, the audio and video were out of sync, as thoroughly discussed in this thread. That problem seems to have been fixed in 8.1.5.9.
However, while the audio and video are now in sync, the subtitles are still progressively out-of-sync. In other words, the subtitles are fine near the beginning of the movie, but as the movie progresses, the subtitles are increasingly mis-aligned with the audio.
The BD in question is "Real Steel," and I'm using the m2ts.ac3.high_quality profile.
