How does one remove the video for clips such as the ones here, here, or here for example on a DVD using a Mac?
Every single DVD, Blu-ray, even HD-DVD begins with a warning that it is illegal to reproduce the source material for any reason -whether you gain from it financially or not. So I don't think it would be within the site's rules to discuss how to do it here. With that said, there are probably about 1,000,000 other sites where it is openly discussed.
