I had similar problems with one of my DVDs.  I think one of the manufacturers 
uses this as a "security" feature.

You could try adding the '-M 3' (in the US use -M 4) option to transcode (in 
the GUI), or if that doesn't work, try '-D nnn' where nnn is a guess at how 
many frames to shift by.  For your deviation try +40 or -40, but I could be 
totally wrong about how big numbers to use.

Test it by transcoding only the first 3 minutes, and keep on trying until 
you've got it about right :-)

Good luck,
