That is the message I got when I installed the new version of Convertxtodvd. I was using version 3.73 and I decided to upgrade to the newer version 4.13. Anyway I never had any problems with this software before. The conversion and burn worked and when I went to shut the program down I got the message, "ConvertXtodvd transcoder has stopped working."I went to VSO's website forum and there's not a whole lot about the error. They did tell us to come here and see if anything can be done. I think that they believe it's either 3rd party software,(but why wouldn't my earlier versions fail?) or it's a Vista issue. Maybe someone here has a suggestion.
