I want to post comp video to YT. I have a DVD. I have a MacBook Pro. I am totally flummoxed by the process. How do I get the files off the dvd, which files do I get, do I save them somewhere as .mpeg files or quicktime, or what? Once I do that, I think the actual uploading won't be so hard. I would be deeply grateful for any help. I feel like a dunce.
