As said, I don't know very much about it but I suspect
it was an interlaced stream at some point, and was
telecined later (50i -> 29.97 telecined).

Imo, that would be very helpful!
Ideally, you would run the following on the original DVD:
$ mplayer dvd:// -dumpstream
$ mplayer dvdnav:// -dumpstream
The resulting file can be cut with dd, a few minutes
that allow to see A/V sync would be great!
(Perhaps including the scene you already provided.)
I can then report the problem to the fieldmatch
Thank you, Carl Eugen
