A dub usually refers to a copy. You can dub a videotape, an audio tape, or even do an audio dub on videotape, where you copy only the audio track without disturbing the video. VirtualDub allows you to perform similar operations on your own computer with audio and video files with a little bit more power.
VirtualDub is primarily a linear editing solution; it does not offer general purpose editing capabilities such as splicing or matte effects. It makes an excellent conversion utility, though; you can recompress, clip, and filter the video to your liking.
