I ran another movie-only backup of Stallone's Lock Up last night, this time with LAVF instead of FFDShow. Same result: audio is badly out of sync.

Feeding the original movie file to MediaInfo revealed something I don't remember seeing on a Blu-ray before. Here's the details of the first audio track:

Code:

Audio #1
ID                               : 4352 (0x1100)
Menu ID                          : 1 (0x1)
Format                           : DTS
Format/Info                      : Digital Theater Systems
Format profile                   : MA
Muxing mode                      : Stream extension
Duration                         : 1h 48mn
Bit rate mode                    : Variable
Channel(s)                       : 6 channels
Channel positions                : Front: L C R, Side: L R, LFE
Sampling rate                    : 48.0 KHz
Bit depth                        : 24 bits
Video delay                      : 624ms

624 milliseconds sounds about right for how much the audio is out of sync on the movie-only backup. That same delay is listed for every audio track.
