I just started using Avi2dvd by TrustFM and for some reason, the audio stream is not loading when I press the "Load file" button (I'm converting a Windows Moviemaker project from .wmv to a Video_TS and an Audio_TS so it can be turned into an .iso file in order to upload to Lulu.com where it will be sold as a VIDEO DVD and playable on a DVD player). Does anyone know why this is happening and how to fix it? The audio associated with the video is in .AIFF format created with Garage Band.
