If you use OSEx, make sure you do it in DVD Image mode. It takes longer, but you don't get errors like in the DVD Folder mode. Once you have the image, mount it (by renaming the .IMG to .dmg and double-clicking on it), and then navigate to its VIDEO_TS folder in DTOX. Another (and quicker) alternative is to use DVD Backup to get the VIDEO_TS folder on your HD, as it's faster and usually works for me. Hope that helps.
