From the developer:
DVDx 4.0 is an audio/video encoder as well as a powerful DVD copier.
DVDx 4.0 is very easy to use: open a DVD or file in the player, play it with audio/subtitle of your choice ; encode a short preview and play it to ensure it's what you expect, and then start the whole encoding job which can take about one hour but you're quiet sure to get a very good result
