Audio out of sync.

We got a DVD player recently that plays divx films using a USB pen. The thing is sometimes when I copy and paste onto the pen drive when I play them on the DVD player the audio is out of sync with the picture. This does not always happen however.
My question is whether or not there is a definite way to transfer onto the pen drive to avoid this. Also if this does occur, is there a way to rectify it on the pen drive or will I have to delete and start a new copy and paste?

Try copying onto a DVD-RW.

If the drive is anything like mine, it's USB1. The DVD player has greater throughput, so video is usually smoother. Your issue may be due to the same problem.
