yes I figured but all the resets occured on a DVD chapter boundary 
(exemple on DNA2 DVD1 chapters 1-5 have no reset then a reset at chapter 
6, no reset until chapter 9.....)

in fact using the slave mode I could calculate the timings if I could 
have the slave mode working.....
It seems to work when I type on the mplayer xterm but remote don't work 
(ie redirecting using a fifo or a pipe the control output to mplayer 
input).....
the way I thought to have the things working is to do
code in C that is translated to SH
printf ("pause");   //put in pause
while (not escape)
   {
    printf ("pause");  //remove pause
    scanf("%c",&mychar);
    if (mychar == 'a')
       {
        time+=10;
        printf("seek %d type=2", time); //do absolute seek
        }
    else
....
    printf ("pause"); //go back to pause
    }
return time
