So I have this .mp4 file I'm trying to convert to DVD with Visual Hub. It converts fine but when I burn it the audio and video start out in sync but somewhere along the lines they are no longer in sync. I've not change any of the settings for Visual Hub and it only happens when I convert this particular file, which plays normally. I'll open the DVD and check the .vob files in VLC Player and the audio is out of sync in them as well. I have the log file if it helps.
