When I try to back up my movies that are on DVD (because I am moving overseas for two years) the movies only play almost to the end but then stop. I'm using Mac The Ripper and am using title only extraction which I thought was the way to do it. I know that you can rip the whole thing and then use Mac DVD player to watch the movie but I want to be able to view the movies on a TV using my external hard drive. How do I fix this?
