I'm running into audio sync problems right after authoring using IFO edit. Here's what I was trying to do. I was trying to convert a Divx file to DVD-R. I used virtual dub first to extract the video, then save the audio as a .wav file.

The next thing I did was go into TMPGenc to convert the file to MPEG2 DVD format. Then, I went to MPEG tools and demultiplexed the save MPEG2 file, the format created a .m2v and .mpa file.

Then I went into IFOEdit then selected Author, to create the .VOB files. And finally burned it to DVD-R using Nero. By the time I played my DVD, it was totally out of sync on the audio. Any suggestions?
