Sounds like a mouse

[martin86]

Every time a movie clip to another format, the audiopart op my converted clip sounds like mices.

I have tried to convert from the formats: MPG and AVI. I have tried to convert to the formats: MPEG, AVI and WMV.

What is wrong, and how can I fix it? If it is something about codec or the like, please advise me, where to get the right one.
