Depends what the source files are. If they are say avi's then you could Demux and remux the stream with VirtualDubMod, however you may need to adjust the length/speed of the audio before remuxing.
You could use AVISynth:
video = avisource("goodvideo.avi",false)
audio = mpasource("goodaudio.mp3")
audiodub(video,audio)
delayaudio(-1)<--change value
etc. to test out different values. Also the timewarp function.

Load the file in virtualdubmod.
Select Streams, stream list.
Right click the audio stream.
Select Full Processing.
Select File, save .wav
Give it a name and save it.
There's your audio.

I guess I should have said, "Load your original movie file", not just "file".
What you demuxed is useless, delete it.
Extract audio as I explain above.
If you want a video file with no audio (a wasted step really) select Audio, no audio, then save avi.
Once you have your audio .wav file, you can encode the video to mpeg in any good encoder, using the extracted .wav as the audio source, and your original avi as video source.
If you have sync problems, you'll need to sort out audio delay in something like Goldwave.

I wouldn't say that it was useless. Sounds like it is just missing a file extension. For instance if the source used mp3 audio then you would just add .mp3.

no, it was a 'file' it had no purpose, no extension for a reason.

So if I take an mp3 and remove the .mp3 extension then it is useless?
