     It is probably hard-coded telecined frames.  I have noticed this 
on 3 of my 13 DVDs so far.  I just posted a rather long message to 
mplayer-dev-eng about it with the subject "Some thoughts on telecine 
artifacts".  I haven't played the DVDs with a Windows DVD player yet, 
I guess I'll have to see if I can find the InterVideo WinDVD CD-ROM 
that came with my DVD-ROM drive.  If it plays these DVDs without 
telecine artifacts, that will be encouraging, because maybe that 
will mean that there is a way to detect the IVTC offset and/or a 
change in the 3:2 sequence during a hard-coded 29.97 FPS segment.
