Video playback with audio problem.

[SE14man]

Hi there,

A few of my videos.. and ONLY a few of them have recently started making a very strange sound on playback. Almost like it is playing back 10 times as fast. I know its not the file as it was fine the other day. Other avis play fine though, and windows audio files play fine in the sound properties aswlel as mp3s. I have tried the same AVI's on 5 different media players and get the same result.
I have a link here with a sample of the audio i was tgetting to see yif you lot can maker out what the problem is.

I personally think it could be down to a certain codec going bad or something but was wondering what you lot think.

Here is the audio from the fast sounding AVI file.

I've just been flicking through some more films and it seems to be that music and sound effects are working fine, but voices aren't playing.
