Ok now I understand where the problem comes from.

But MPsub format gives relative position of subtitles,
that is to says, the ellpsed time between to subtitles to display.
For example for spumus xml file gives :

<?xml version="1.0" encoding="iso-8859-1" ?>
<subpictures>
   <stream forced="no">
     <spu lang="fr" start="00:00:21.960" end="00:00:24.840">
       <line row="22" col="01"><white>La couleur pourpre</white></line>
     </spu>
     <spu lang="fr" start="00:02:04.320" end="00:02:06.480">
       <line row="22" col="01"><white>Ma soeur, on me l'ôtera 
pas.</white></line>
     </spu>
     <spu lang="fr" start="00:02:06.840" end="00:02:08.400">
       <line row="22" col="01"><white>Makidada.</white></line>
     </spu>

And the MPsub file gives :

21,96 2,88
       La couleur pourpre

99,48 2,16
       Ma soeur, on me l'ôtera pas.

0,36 1,56
       Makidada.


Then how to begin the mpsub file in absolute format ?

I try to dvb-mplex the vdr file in an mpg, like in the way to do a DVD, 
because then I can encode the produced mpg file with the -sub option.
But dvb-mplex gives this kind of error message in the middle of the muxing.

Error in MPEG stream at offset (bits) 550277797 : supposed marker bit 
not found

Why ?
And How to make a dvd then ?

Thanks for your help.

Nicolas.
