Audio Sync Issues on playback via thumb drive
The answer stems from the combination of the speed of the flash drive and the data rate of the video. The video and audio in most codec are decoded separately once streamed to the computer from the flash drive. Now when the flash drive can't keep up with the speed the video is supposed to be playing then the audio or the video get ahead because the flash drive cannot serve both at the same time. Time for a faster flash drive.
