This happens when I play from the image "burned onto my harddrive, using 
VLC. I haven't tried mounting the image so that another player can run 
it, nor have I tried it directly from the original DVD yet. I'm not sure 
about the play or burn rate, haven't done anything there, just using 
defaults, but that could be added to my list of things to try. I'll let 
you know what I come up with though.
