From an old post, however I couldn't find the answer to this:
What is the video frame duration @23.976 fps?

Next question. I extracted a Dolby THD track to wavs, where the track has a video delay of -32ms.

The log shows (note lines 2 and 7):

Code:
[a03] Extracting audio track number 3...
[a03] This track begins with a non-major frame. <WARNING>
[a03] Extracting TrueHD stream...
[a03] Removing TrueHD dialog normalization...
[a03] Decoding with DirectShow (Nero Audio Decoder 2)...
[a03] DirectShow reports 5.1 channels, 24 bits, 48kHz
[a03] Applying RAW/PCM delay...
[a03] Writing WAVs...
I then converted the wavs to DTS-MA.

So, does the "applying RAW/PCM delay..." mean that I don't have to apply any delay when muxing the DTS track back with the video?
