Hi, A user sent us a AVI/DV file that crashes FFMPEG. The problem seems to be the 'iavs' stream type that it not recognized in AVI. VDM can remux this file fine and then it works in FFMPEG. http://www.matroska.org/~robux4/drdivx/samples/DivXSmall.avi It also crashes AVI-Mux GUI but works fine with MS's splitter in DirectShow.
