In the older version, it use to be under streams but this seems to have disapeared and i have no idea how to remove the spanish audio now. any ideas?
I don't use VirtualDub so I don't know the settings, but if your AVI file has two audio tracks, you can remove one easily using AvimuxGUI. If it has one audio track with 2 channels, different story. http://www.videohelp.com/tools/AVIMux_GUI
yes it is one audio track with two channels. I tried using avimux and it cus out all the sound because its only one audio track.
In this case you need to separate the left and right channels. You can use Audacity. Save only the audio file using VirtualDub and try to remove one of the channels. http://audacityteam.org/wiki/index.php?title=Vocal_Removal
