It may be some inconsistency in the HEVC stream generated by X265, or possibly FFMPEG (used for frame serving) could be losing frames... I really don't know. I don't think it is the audio, as it doesn't necessarily get reencoded, and it is handled no differently than with previous BD-RB versions.
I haven't figured out why this is happening yet, but if and when I do I'll release a test version here on Doom9. The biggest problem is that it takes anywhere between 10 and 18 hours for my system to do a full movie (even at the fastest encode speed and using one-pass ABR)... so you can only do so much in a day.
I think I'll do a couple encodes using AVISYNTH just to eliminate the FFMPEG possibility -- but even if it works correctly that's not a long term solution as it would also be losing the HDR and 10 bit attributes during encode.

Weak, very weak
