Oke I tried to add the subtitle with avisynth. I followed this guide:
http://www.dvdrhelp.com/forum/userguides/87065.php#4 
Avisynth and TextSub, Scenario 4 --AVISYNTH-- . Thats what I followed. It was'nt hard but when I played the new avs. script in WMP it happend something weird

The subtitle was playing on the movie (divX). But after a while the subs was going to fast, I hope you know what I mean... The subs had already been showed when they should have on the movie

Maybe you call it, out of sync or something

Oke hope you understnd me "the subs was to fast for the movie". And please I could need some help,I'm stuck as usual
