Found it
OK. Following helpful advice from some posters in this forum, I managed to extract and demux the audio, then look at the wave forms on screen.
It turns out (I kid you not) that the audio started as a simple stereo track, with the background music on the left channel and the voice-over on the right (known as pingpong stereo in the days of Vinyl records) which was then, for no apparent reason, upmixed to DS5+1, BUT... because some channels are 180 degrees out of phase, either audio _or_ voiceover disappears when being downmixed back to stereo during playback.
Why? I have no idea. This DVD is definitely a private release, and whoever made it didn't do it too cleverly.
Thanks to everyone who helped me get this headache sorted out!!
I'm not in the process of straightening out the audio and will then remux it using MKVtoolnix or some such.
Tnx!!
