hHelp with Track Synchronization

[DanM]

I have a DVD that I ripped to take with me on the road. When I play it back on VLC (or other media players for that matter) the sound is ahead of the video by a few seconds.
I have tried using the VLC's Audio/Video synch tool by putting in a negative number. It doesn't seem to have any effect. I even clicked on the refresh and it didjn't work. I am running th elatest VLC 1.1.7 with Windows 7 operating system. This problem is with several of my ripped files. Any help would be greatly appreciated.
