Sound is garbled

[111hhh111]

Hi.

I have a problem with sounds in files encoded using:
MPEG Layer- 3 Codec (professional) for audio
and MS MPEG-4 v3 for video.

When i play them using Zoom Player and Media Player, the sound is in-sync but very garbled. I opened the files in VirtualDub and they played fine.
Also i have noticed that only smaller files have this problem.

Any help will be apreciated.

****edit*****
I actually haven't encoded the files, i d/l'ed them I thought that maybe i had a codec problem, etc. Sorry if igave the wrong impression.

Assuming the original MP3 file plays alright, try te following:
1. Open file in nandub
2. Set both Video and Audio tabs to Direct Stream Copy
3. Go to File -> Save as AVI... and give a name to the new file
