Get subsync right

[datachild]

Hello,

I've got a sub syncing problem, I don't have very much knowledge on sub synchronization but I read various guides and posts from other users but couldn't find an answer to my problem.

First I describe what I have:
- 2 CD movie, Xvid, 23.97 fps.
- Subs for 2 cd movies which is perfectly synced. (*.srt)
- DVDR movie. 29.97 fps.

What I need:
Synced subs for DVDR movie.

What I managed:
Joined the subs from the 2 CDs. (recalculated times) (*.srt)

Problem:
The subs start out at a good sync for the DVDR. Then slowely it moves off. It gets behind, things are said in the movie and moment later the sub appears.

Question:
How do I get this problem fixed? It is the same movie in Xvid and DVDR. And on the xvid the sync is perfect. How come its not for DVDR and how do I get it synced??

I sure hope somebody can help me
