Can't get a movie to burn

Disney Lilo and Stitch won’t burn. It gets about 80% complete then whatever program I am using freezes completely showing [Not Responding] in the task manager. I’ve tried it with CloneDVD and DVDCopyExpressI had a similar problem copying Cradle to the Grave but eventually got it to do my bidding by simply repeatedly trying. No luck with this movie though. Anyone else have a similar issue or any ideas or what my problem might be? Thanks!


Maybe it’s a mastering error or the disc is damaged at this point. Any scratches on the surface?
