Hello. I've got a DVD with a concert on it with terrible sound quality. However, there was also a CD released with the same recording and this sound quality is fine. So I ripped the DVD to m2v and wav files, remastered the complete wav file (using the CD as source) to replace the original (converted to 48 kHz of course) and wanted to re-author the DVD using IfoEdit. However, when I do so, the resulting DVD has the video part running much too fast (about two times normal speed). The audio is fine however.

Does anyone know if this is a problem in IfoEdit or am I doing something wrong ?
I ripped with DVDdecrypter in IFO mode.
