Quicktime not producing any sound.

Hey everyone,
I just got my new IMac Intel Machine in today and love it. My OS is 10.4.4. A problem I noticed was I moved over my movies from my old iBook G3 OS 10.3.9 and at first they played fine. Then I moved over Windows Media Player. Those also worked fine. Then I moved over VLC and now that has messed things up. My WMP vidoes now say they are not encoded properly or something and have no sound. Most but not all of my mpeg's, mpg's , and avi's also do not have sound. It's very frustrating and annoying and you can imagine. I was just looking to see if any of you have had problems with this also. Thanks!

I can't imagine why that would have happened. I would suggest a permission repair to start.

Yeah it's insane. I was shocked to see it. I might re-download VLC or some of the other programs.

Problem solved. VLC was jacking up the sound in the MIDi sound output part and messing with Windown Media PLayer and Quicktime. I moved the sound down from 192000 to 41000 and it fixed it.
