I was told that AviDemux could demux WMV files. I have WMV files that have only a WMA stream (no video stream). When I open it with AviDemux, it aborts saying the attempt failed, then "could not open the file".
Was I misinformed about the ability to demux a WMV file?
Shall i upload a small sample file?
Try Audacity (you may have to install some "extensions").
