 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
 or
 $ 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 
 maintainer;-)
 
 Thank you, Carl Eugen

Will do, but don't expect anything until December, I'm leaving in the AM to go on holiday for a week.
