VSO convertXtoDVD 5 audio delay problem

[omegads]

Good day to all, i come here today because i have this problem when auditing a DVD using the above software.

I have a MKV file that i see ok on my PC or my BR player using the MKV format, but once i convert it to DVD using the software, the audio moves, the first 2 minutes are ok but after that it starts delaying until you cannot longer understand waht they are saying acording to the video, apart what i saw what that on the last few minutes when the credits where on, there were still voices from the actors from the movie..

on the setup for the software i used for encoding the video 30fps as the original is, and in audio i used atomatic

This is the info from my file.... hope you can help.. thanks

Does this mkv come from makemkv? As it looks like a rip directly from a dvd to mkv. No video reconversion/shrinking. THe variable frame rate mode can cause sync issues when you convert it.

But I would try another dvd converter/author like avstodvd and see how it handles it.
