Well, that was not my aim.
Due to the noise of my CD drive, I copy the film on the hard disk before
watching it. Then mplayer CD1.avi CD2.avi.

OK, I will use this solution. Thank you for your answer.

Is it the same reason the makes midentify report ID_LENGTH=6720 while the
real length of the movie is 8660s ? And is there a way of getting this
length other than reading it on the DVD box ?
