I have the same project: a set of region 0 PAL DVDs I want to convert to region 0 NTSC DVDs. The question not asked or answered here is the following: will Digital Media Converter also convert the menus, special features, and audio tracks from the PAL DVDs? I want to convert the entire DVD, not just the movie.
My plan is to rip the full DVD to my hard drive using DVD Shrink. Use Digital Media Converter to convert the files to NTSC. Then use Nero Express to burn a DVD video disc. I should have an exact copy of the DVDs with no quality loss only in NTSC format.
