After outputting an AVI file from Vegas Video 3.0 I am unable to use it in any ULead product. I use ULead DVD Workshop SE to create my DVDs. At the moment I am having to import the Vegas files into Windows Movie Maker (which reads them fine) and then resave them as AVIs before importing them into DVD Workshop. A real pain. Does anyone know if this might be a codec issue with Vegas, and if so, how I can fix it? I have no compatability problems with any of the ULead created AVI files. All programs will read them fine (including Vegas!)
