Audio Damaged After Video Conversion. How to Fix?

[Fluoresce]

Hi! I'm new here, so please bear with me . . .

I upload videos to YouTube. I have uploaded one particular video multiple times. Although it plays fine on my PC, once uploaded, I observe an audio problem:

(Note that I will delete the above video once the problem is fixed.)

Can anyone tell me what might be wrong with the audio?

Some Things You Should Know

YouTube converts its videos. The video above was originally in avi format (see full details below). According to what I've read, it was transcoded into flv format after being uploaded. The video frame size was scaled to no larger than 320x240, the frame rate was altered to between 25 and 30 frames per second, the video data rate was reduced to somewhere around 200 kbps, and the audio was reduced to mono and transcoded to a lower bit rate.

It's this conversion process which produces the problem. I've tried converting and uploading the video in different formats myself, including avi, wmv, mpeg and flv, but the problem persists. There is no difference between this and other videos that I have uploaded, yet only this one has encountered this problem. Can anyone help?

Below are the video's original details. Any help will be much appreciated.
