I am facing problem in audio while using VLC player

Hi,
I know this is not the correct place to post as my post is related to VLC player and I am using windows Xp. Windows xpe forum is full of spammers so I thought of posting here. I am facing problem in audio of the video when I download any video from youtube, vimeo or any movie from movie25

When I use the forward option, then only I get this problem.
