I am trying to convert some videos using SUPER video converter but after converting I notice that the audio is out of sync and gets worse gradually as the video goes on. In SUPER I'm setting the output container as avi so I can put it onto dvd, and its using ffmpeg, if that helps. The video files were originally in flv format and worked fine. This program has so many options I could change but I don't know what they all do. Any help would be greatly appreciated. Thanks.
