My sound doesn't come uot properly.

I'm inputting mpg's into Flash (MX 2004).
The film quality seems to be OK, but the ound come out grainy.
I've got people talking on my video footage and all the voices come out as though they've got a lisp!

What am i doing wrong?

Any help would be appreciated.

Thanks.

May be audio compression, what are u using? try uncompressed audio see if that works.
Right-click on it choose properties, the 2nd tag, next to general see what kind of audio compression you have.
