Well I have this problem:

I author my dvd from a divx with tmpgenc,ac3fix,ifoedit,nero

Well the problem is that all my dvd's work on my yamada home cinema dvd-player without a problem.

When I try them in a lifetec the sound is not in syncro with the picture.
The weirdest of al is that I have finding nemo in divx and converted it to a dvd and that movie played normal.
Does this anything to do that the lifectec doesn't support ntsc movies?
because finding nemo was in 25fps and burned it with pal.
Does this has anything to do with it?

Or has it to do with the sound?
Like finding nemo was mp3 sound and the other movies was ac3.

If it has to with the fps?
Can't I just a movie with 23.9fps author with tmpgenc as a pal standard?

I hope someone is possible to help me?
