OK, I don't really care who it is that asks the/a question, I don't think such harsh responses are nearly necessary. Sheesh. Yes, this may not officially be a 'help' forum, but more often than not more general video help questions get put here, so it's easy to make the mistake. If a mod wants to move it, it would not be out of line, however.
Nick- there are a number of ways to remove the audio from your files. It's easiest to do it by simply not capturing it in the first place. Assuming this isn't an option, if you're using Premiere, you can simply unlink the Audio and Video (rigiht click on the clip on the timeline and select 'unlink audio and video') and then delete the video.
Otherwise, probably the easiest way is to use VirtualDub, which can be DL'd free (legally). Just do a quick search for it or go to doom9.org and grab it from there. You can open up your video file, select "Direct Stream Copy" under the Video menu and "No Audio" under the Audio and then "Save as AVI" and save it as whatever you want. VDub is a very useful program to have around otherwise as well, as is outlined in the guides. Good luck!
BTW, It's far from uncommon for us to as for more information about a problem or what you're trying to do- in many cases, there are many possible answers, and the more information we have the better we can figure out what the right answer to give likely is...
