Werid Quicktime problem

Hey All

I have just ripped and converted [xvid] a couple of my DVD's using Mactheripper and then D-Vision 3. I did some last week and they were fine.

When I play them on VLC they are fine, but with Quicktime the movie ends prematurely and displays a white screen to mark the end of the movie. At first I thought it was the way I converted the file, but I converted it a few times now and get the same results.

Any ideas?

Thanks in advance.
