Help with mono-recorded audio

Help! :)

I need to find a way to transform the recorded audio from mono to stereo. I used an external clip-on-shirt mic with my HDV camera in order to make the interview parts of the local rock band I was shooting more professionally-audible ( http://eugenia.blogsome.com/2007/08/26/drist-report-on-their-3rd-music-album/ ), but most such mics are mono and so only one speaker plays back during the voice track (the rest of the video is truly stereo).

How exactly (step by step) do I make a mono signal that is posing as stereo in the timeline, to be truly stereo? I know it's possible because YouTube does that automatically when you upload a video there. So while my YouTube video has that problem fixed, my original h.264 exported video (75 MBs, linked from the above page) doesn't, because VMS thinks that the voice track is stereo, while it's not.

Have you considered Audacity? My guess is it should work. I opened a stereo file in Audacidy, then split the two channels. Deleted one, and played with it: left, right, and mono (plays in two channels). Then re-encode and that's it.

I would like to do that on Vegas. Not export to another audio editor and then try (in vain) to resync the A/V... I'd rather leave it sounding weird in mono than go through the hassle of exporting/importing/resyncing audio... There's got to be a way to fix this in Vegas because most clip-on mics are mono so my situation is not unique...

Have you already tried this: in Vegas, right-click on the audio event, click channels? There are five settings there to play with. It seems to work for me.

That seems to be it, thanks!
