Ok, I have a mpeg file that has 2 audio tracks, or at least I assume it does (one is music that was added by the uploader the other is the original track which you can distinctly hear in the background) and I'm hoping to strip the audio from the file and then re-attach just the original track. I tried it through virtualdub but it give me a "cannot load decompressor for wmv1" error. So I'm stuck. Is this possible? If so, can someone give me an idea on how to go about it?
